The Intel® Edison is an ultra small computing platform that will change the way you look at embedded electronics. Each Edison is packed with a huge amount of tech goodies into a tiny package while still providing the same robust strength of your go-to single board computer. Powered by the Intel® Atom™ SoC dual-core CPU and including an integrated WiFi, Bluetooth LE, and a 70-pin connector to attach a veritable slew of shield-like “Blocks” which can be stacked on top of each other. It’s no wonder how this little guy is lowering the barrier of entry on the world of electronics!

The GPIO Block is a simple breakout board to bring the GPIO from the Intel® Edison to the user. Bread board friendly, the GPIO Block provides access to all basic GPIO, PWM, and UART2 pins. All GPIO is level shifted to a selectable 3.3v or VSYS. The GPIO add-on also provides access to all three power rails found on the Intel® Edison. 3.3v, 1.8v, VSYS, and GND are accessible for bread board prototyping. Note: Since the level shifting is accomplished through a auto direction sensing translator, driving high current components (Such as Relays, Motors, and high power LED’s) will require an external switch. See the Hookup Guide to learn more.

The Battery Block brings a single cell LiPo Charger and 400mAh battery to power an Intel® Edision and expansion blocks. The Battery board can be used with an external battery to increase runtime of your Edison which can be plugged in with a micro USB cable to deliver a 500mA charge current. Additionally, the power switch removes the battery from the Edison while allowing it to charge via the microUSB cable. If you need more battery life, it is possible to gently peel the battery off, de-solder the wires, and replace it with a larger cell. If you remove the battery, it is also possible to expose the expansion header to continue stacking blocks. It may be necessary to find an alternative mounting point for your battery in this case. Go wireless with Edison!

The 9 Degrees of Freedom Block for the Intel® Edison uses the LSM9DS0 9DOF IMU for full-range motion sensing. This chip combines a 3-axis accelerometer, a 3-axis gyroscope, and a 3-axis magnetometer. By default, the IMU is connected to the Edison through the I2C bus. Each sensor in the LSM9DS0 supports a wide range of, well, ranges: the accelerometer’s scale can be set to ± 2, 4, 6, 8, or 16 g, the gyroscope supports ± 245, 500, and 2000 °/s, and the magnetometer has full-scale ranges of ± 2, 4, 8, or 12 gauss. Additionally, the LSM9DS0 includes an I2C serial bus interface supporting standard and fast mode (100 kHz and 400 kHz) and an SPI serial standard interface.

This Block adds eight channels of PWM control to the Edison’s I2C bus. While the PWM output can be used for any generic PWM application, it is specifically intended to provide drive control for up to eight standard hobby-type servo motors. To that end, it has an independent input for supply voltage for the servos above the normal range of the Edison, and 8 connections that support the most common pinout of hobby servo motors. The PCA9685 equipped on this board has an independent clock that can be operated at 50Hz, for servo control; at that frequency, the 12-bit resolution of the device provides approximately 200 steps of resolution for a servo motor.

The PCA9685 can be used as an open collector current driver for LEDs up to 25mA as well. Six solder jumpers allow the user to attach up to 63 of these cards to a single Edison, or to adjust the address of the PCA9685 to avoid collision with other addresses on the bus.

Since the Edison offers a large number of GPIO and communication bus pins, these pins can be mapped to the exact same footprint as the Raspberry Pi B’s GPIO header. The Pi Block lets you use your existing Raspberry Pi B peripherals and expansion boards with your Edison while still providing level-shifted access to basic GPIO, PWM, UART, I2C, and SPI communication! This block combines the functionality of the GPIO Block and I2C Block with additional features to streamline development.

The Console UART Block delivers power to the Intel® Edison while providing a simple console interface via a FTDI cable. This is the most minimal solution to get started using the Intel® Edison. This board can supply 4V and up to 500mA of current to power the Edison passed through it’s VSYS line and any other expansion boards you may add to your stack. This is a great board for low power applications that won’t require constant console access. By removing the FTDI USB-UART from the board, current consumption is minimal. When the FTDI cable is not inserted, it will be necessary to provide external power to the board.

Note: The 3.3V FTDI breakout will NOT work with this block, but the 5V version will.

Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well.  We do sell these on a breakout, but maybe you wanna just put this in your own project PCB.

These modules are very easy to hand solder, with big pads! We have this part in the Adafruit Eagle library (ESP12) - the extra pads don't appear but they are not usable anyways.

Comes with 4MB flash chip, ESP processory, and onboard antenna. These come pre-progammed with the NodeMCU Lua firmware, so you are ready to rock. Some extra parts will be needed to get this going, check out the HUZZAH schematic for the extra components we recommend

For advanced users only! This product is just the module - which can be difficult to use.  Click here if you're looking for the Huzzah ESP8266 Breakout!

The SparkFun ESP8266 Thing is a breakout and development board for the ESP8266 WiFi SoC – a leading platform for Internet of Things (IoT) or WiFi-related projects. The Thing is low-cost and easy to use, and Arduino IDE integration can be achieved in just a few steps. We’ve made the ESP8266 easy to use by breaking out all of the module’s pins, adding a LiPo charger, power supply, and all of the other supporting circuitry it requires.

Why the name? We lovingly call it the “Thing” due to it being the perfect foundation for your Internet of Things project. The Thing does everything from turning on an LED to posting data with datastream, and can be programmed just like any microcontroller. You can even program the Thing through the Arduino IDE by installing the ESP8266 Arduino addon.

The SparkFun ESP8266 Thing is a relatively simple board. The pins are broken out to two parallel, breadboard-compatible rows. USB and LiPo connectors at the top of the board provide power – controlled by the nearby ON/OFF switch. LEDs towards the inside of the board indicate power, charge, and status of the IC. The ESP8266’s maximum voltage is 3.6V, so the Thing has an onboard 3.3V regulator to deliver a safe, consistent voltage to the IC. That means the ESP8266’s I/O pins also run at 3.3V, you’ll need to level shift any 5V signals running into the IC. A 3.3V FTDI Basic is required to program the SparkFun ESP8266 Thing, but other serial converters with 3.3V I/O levels should work just fine as well. The converter does need a DTR line in addition to the RX and TX pins.

"You see, wire telegraph is a kind of a very, very long cat.  You pull his tail in New York and his head is meowing in Los Angeles.  Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there.  The only difference is that there is no cat."

Sending data over long distances is like magic, and now you can be a magician with this range of powerful and easy-to-use radio modules. Sure, sometimes you want to talk to a computer (a good time to use WiFi) or perhaps communicate with a Phone (choose Bluetooth Low Energy!) but what if you want to send data very far? Most WiFi, Bluetooth, Zigbee and other wireless chipsets use 2.4GHz, which is great for high speed transfers. If you aren't so concerned about streaming a video, you can use a lower license-free frequency such as 433 or 900 MHz. You can't send data as fast but you can send data a lot farther.'

Also, these packet radios are simpler than WiFi or BLE, you dont have to associate, pair, scan, or worry about connections. All you do is send data whenever you like, and any other modules tuned to that same frequency (and, with the same encryption key) will receive. The receiver can then send a reply back. The modules do packetization, error correction and can also auto-retransmit so its not like you have worry about everything but less power is wasted on maintaining a link or pairing.

These modules are great for use with Arduinos or other microcontrollers, say if you want a sensor node nework or transmit data over a campus or town. The trade off is you need two or more radios, with matching frequencies. WiFi and BT, on the other hand, are commonly included in computers and phones.

These radio modules come in four variants (two modulation types and two frequencies) The RFM69's are easiest to work with, and are well known and understood. The LoRa radios are exciting and more powerful but also more expensive.

This is the 900 MHz radio version, which can be used for either 868MHz or 915MHz transmission/reception - the exact radio frequency is determined when you load the software since it can be tuned around dynamically. We also carry a 433 MHz version here. These are +20dBm LoRa packet radios that have a special radio modulation that is not compatible with the RFM69s but can go much much farther. They can easily go 2 Km line of sight using simple wire antennas, or up to 20Km with directional antennas and settings tweakings

Packet radio with ready-to-go Arduino libraries

Uses the license-free ISM band: "European ISM" @ 868MHz or "American ISM" @ 915MHz

Use a simple wire antenna or spot for uFL or SMA radio connector

SX1276 LoRa® based module with SPI interface

+5 to +20 dBm up to 100 mW Power Output Capability (power output selectable in software)

~100mA peak during +20dBm transmit, ~30mA during active radio listening.

Range of approx. 2Km, depending on obstructions, frequency, antenna and power output

All radios are sold individually and can only talk to radios of the same part number. E.g. RFM69 900 MHz can only talk to RFM69 900 MHz, LoRa 433 MHz can only talk to LoRa 433, etc.

Each radio comes with some header, a 3.3V voltage regulator and levelshifter that can handle 3-5V DC power and logic so you can use it with 3V or 5V devices. Some soldering is required to attach the header. You will need to cut and solder on a small piece of wire (any solid or stranded core is fine) in order to create your antenna. Optionally you can pick up a uFL or SMA edge-mount connector and attach an external duck.

This is a simple to use, USB to serial base unit for the Digi XBee line. This unit works with all XBee modules including the Series 1 and Series 2.5, standard and Pro version. Plug the unit into the XBee Explorer, attach a mini USB cable, and you will have direct access to the serial and programming pins on the XBee unit.

The highlight of this board is an FT231X USB-to-Serial converter. That’s what translates data between your computer and the XBee. There’s also a reset button, and a voltage regulator to supply the XBee with plenty of power. In addition, there are four LEDs that’ll help if you ever need to debug your XBee: RX, TX, RSSI (signal-strength indicator), and power indicator.

This board also breaks out each of the XBee’s I/O pins to a pair of breadboard-compatible headers. So if you want to make use of the XBee’s extended functionality, you can solder some header pins into those, or even just solder some wire.

Feather is the new development board from Adafruit, and like its namesake it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores. This is the Adafruit Feather M0 WiFi w/ATWINC1500 - our take on an 'all-in-one' Arduino-compatible + high speed, reliable WiFi with built in USB and battery charging. Its an Adafruit Feather M0 with a WiFi module, ready to rock! We have other boards in the Feather family, check'em out here.

Connect your Feather to the Internet with this fine new FCC-certified WiFi module from Atmel. This 802.11bgn-capable WiFi module is the best new thing for networking your devices, with built-in low-power management capabilites, Soft-AP, SSL TLS 1.2 support and rock solid performance. We were running our adafruit.io MQTT demo for a full weekend straight with no hiccups (it would have run longer but we had to go to work, so we unplugged it). This module is very fast & easy to use in comparison to other WiFi modules we've used in the past.

This module works with 802.11b, g, or n networks & supports WEP, WPA and WPA2 encryption.  You can connect to your own WiFi networks or create your own with "Soft AP" mode, where it becomes its own access point (we have an example of it creating a webserver that you can then control the Arduino's pins). You can clock it as fast as 12MHz for speedy, reliable packet streaming. And scanning/connecting to networks is very fast, just a second or two.

You might be wondering why use this when you can get a HUZZAH Feather? Well, you get:

A highly-capable Cortex M0+ processor with ton more I/O pins, lots of 12-bit ADCs, a 10-bit DAC, 6 total SERCOMs that can each do SPI, I2C or UART (3 are used by the existing interfaces, leaving you 3), plenty of timers, PWMs, DMA, native USB, and more (check out the Datasheet)

The ATWINC has much lower power usage, about 12mA for the WINC & 10mA for the ATSAMD21 with auto-powermanagement on for the WiFi and no power management for the ARM. With manual power management, you can get the WiFi module to down to ~2mA by putting it to sleep.

This is compared to the ESP's ~70mA average current draw, and whose deep sleep mode requires a WDT reset.

We also found that we could stream more reliably (less 'bursty') with the ATWINC, although altogether the ESP has higher throughput.

You also dont have to 'yield' all the time to the WiFi core, since its a separate chip. You get full reign of the processor and timing

Of course, both WiFi-capable Feathers have their strengths and tradeoffs, & we love both equally!

At the Feather M0's heart is an ATSAMD21G18 ARM Cortex M0 processor, clocked at 48 MHz and at 3.3V logic, the same one used in the new Arduino Zero. This chip has a whopping 256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x as much)! This chip comes with built in USB so it has USB-to-Serial program & debug capability built in with no need for an FTDI-like chip. For advanced users who are comfortable with ASF, the SWDIO/SWCLK pins are available on the bottom, and when connected to a CMSIS-DAP debugger can be used to use Atmel Studio for debugging.

To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don't need to use a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. We also tied the battery through a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.

Here's some handy specs! Like all Feather M0's you get:

Measures 2.1" x 0.9" x 0.3" (53.65mm x 23mm x 8mm) without headers soldered in. Note it is 0.1" longer than most Feathers

Light as a (large?) feather - 6.1 grams

ATSAMD21G18 @ 48MHz with 3.3V logic/power

256KB FLASH, 32KB SRAM, No EEPROM

3.3V regulator (AP2112K-3.3) with 600mA peak current output, WiFi can draw 300mA peak during xmit

USB native support, comes with USB bootloader and serial port debugging

You also get tons of pins - 20 GPIO pins

Hardware Serial, hardware I2C, hardware SPI support

8 x PWM pins

10 x analog inputs

1 x analog output

Say "Hi!" to the WICED Feather! Perfect for your next Internet connected project, with a powerful processor and WiFi core that can take anything you throw at it - this Feather is WIC(K)ED AWESOME!

Feather is the new development board from Adafruit, and like its namesake it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores. This is the Adafruit WICED Feather - it's our most powerful Feather yet! We have other boards in the Feather family, check'em out here.

The WICED Feather is based on Cypress (formerly Broadcom) WICED (Wireless Internet Connectivity for Embedded Devices) platform, and is paired up with a powerful STM32F205 ARM Cortex M3 processor running at 120MHz, with support for TLS 1.2 to access sites and web services safely and securely.

We spent a lot of time adding support for this processor and WiFi chipset to the Arduino IDE you know and love. Programming doesn't rely on any online or closed toolsets to build, flash or run your code. You write your code in the Arduino IDE using the same standard libraries you've always used (Wire, SPI, etc.), compile locally, and the device is flashed directly from the IDE over USB.

Since the WICED Feather is based on the standard Adafruit Feather layout, you also have instant access to a variety of Feather Wings, as well as all the usual standard breakouts available from Adafruit or other vendors.

After more than a year of full time effort in the making, we think it's the best and most flexible WiFi development board out there, and the easiest way to get your TCP/IP-based project off the ground without sacrificing flexibility or security. We even cooked in some built-in libraries in the WiFi core, such as TCP client and Server, HTTP client and server, and MQTT client (with easy Adafruit IO interfacing). It can even work with Amazon AWS IoT!

Please note: this is a really cool product but it's also very advanced and there may be firmware updates, tweaks and fixes as we have more people use it. For that reason we are calling this the Developer Edition! This chipset is not identical to the Arduino standard-supported Atmega series and many libraries that are written specifically for AVR will not compile or work with the STM32!

The WICED Feather has the following key features:

Measures 2.0" x 0.9" x 0.28" (51mm x 23mm x 8mm) without headers soldered in

Light as a (large?) feather - 5.7 grams

STM32F205RG 120MHz ARM Cortex M3 MCU

BCM43362 802.11b/G/N radio

128KB SRAM and 1024KB flash memory (total)

16KB SRAM and 128KB flash available for user code

16MBit (2MB) SPI flash for additional data storage

Built in Real Time Clock (RTC) with optional external battery supply

Hardware SPI and I2C (including clock-stretching)

12 standard GPIO pins, with additional GPIOs available via SPI, UART and I2C pins

7 standard PWM outputs, with additional outputs available via SPI, UART and I2C pins

Up to eight 12-bit ADC inputs

Two 12-bit DAC outputs (Pin A4)

Up to 3 UARTs (including one with full HW flow control)

TLS 1.2 support to access secure HTTPS and TCP servers

On board single-cell LIPO charging and battery monitoring

Fast and easy firmware updates to keep your module up to date

Based on the excellent community-supported Maple project

Comes fully assembled and tested, with a USB bootloader that lets you quickly use it with the Arduino IDE. We also toss in some header so you can solder it in and plug into a solderless breadboard. Lipoly battery and MicroUSB cable not included (but we do have lots of options in the shop if you'd like!)

Our learn guide will show you everything you need to know to get your projects online, and connected to the outside world!

For years we've seen all sorts of microcontroller-friendly WiFi modules but none of them were really Adafruit-worthy. Either they were too slow, or too difficult to use, or required signing an NDA, or had limited functionality, or too expensive, or too large. So we shied away from carrying any general purpose microcontroller-friendly WiFi boards.NO LONGER! The CC3000 hits that sweet spot of usability, price and capability. It uses SPI for communication (not UART!) so you can push data as fast as you want or as slow as you want. It has a proper interrupt system with IRQ pin so you can have asynchronous connections. It supports 802.11b/g, open/WEP/WPA/WPA2 security, TKIP & AES. A built in TCP/IP stack with a "BSD socket" interface. TCP and UDP in both client and server mode, up to 4 concurrent sockets. It does not support "AP" mode, it can connect to an access point but it cannot be an access point.

New! As of 3/20/2014 we are shipping v1.1 which adds a tri-state buffer to the MISO pin so that you can use the CC3000 with other SPI devices on the same bus.

We wrapped this little silver modules in a tidy breakout board. It has an onboard 3.3V regulator that can handle the 350mA peak current, and a level shifter to allow 3 or 5V logic level. The antenna layout is identical to TI's suggested layout and we're using the same components, trace arrangement, and antenna so the board maintains its FCC emitter compliance (you'll still need to perform FCC validation for a finished product, but the WiFi part is taken care of). Even though it's got an onboard antenna we were pretty surprised at the range, as good as a smartphone's.Each order comes with one fully assembled and tested breakout and a small stick of header you can use to solder in and plug into a breadboard. We don't have a detailed tutorial yet but to get you started, we've got a fully working Arduino library that is based off of TI's codebase but adapted for use with the AVR. We also have example code showing how to scan the SSID's, connect to your access point and run DHCP, do a DNS lookup to IP address, ping a site and connect to a remote TCP socket such as a website and print out the page.Please note the hardware is good, but the library code does not yet support all of the CC3000's functionality. At this moment, SSID scanning, connection, DHCP, DNS lookup, ping, and UDP/TCP client & TCP server connections (eg connect to a website and grab data or host a very short website) all work and are tested with example code. Check out our tutorial for wiring and Arduino library downloadsFor use with Arduino Uno, Leonardo/Micro & Mega only at this time - we'll try to get the code ported to the Due at some point but no ETA.

Adafruit CC3000 Breakout with Onboard Ceramic Antenna (0:16)

Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well. While this chip has been very popular, its also been very difficult to use. Most of the low cost modules are not breadboard friendly, don't have an onboard 500mA 3.3V regulator or level shifting, and aren't CE or FCC emitter certified....UNTIL NOW!

The Adafruit HUZZAH ESP8266 breakout is what we designed to make working with this chip super easy and a lot of fun. We took a certified module with an onboard antenna, and plenty of pins, and soldered it onto our designed breakout PCBs. We added in:

Reset button,

User button that can also put the chip into bootloading mode,

Red LED you can blink,

Level shifting on the UART and reset pin,

3.3V out, 500mA regulator (you'll want to assume the ESP8266 can draw up to 250mA so budget accordingly)

Two diode-protected power inputs (one for a USB cable, another for a battery)

Two parallel, breadboard-friendly breakouts on either side give you access to:

1 x Analog input (1.0V max)

9 x GPIO (3.3V logic), which can also be used for I2C or SPI

2 x UART pins

2 x 3-6V power inputs, reset, enable, LDO-disable, 3.3V output

One breakout at the end has an "FTDI" pinout so you can plug in an FTDI or console cable to upload software and read/write debugging information via the UART. When you're done with your coding, remove the cable, and this little module can be embeded into your project box.

Each module comes pre-loaded with NodeMCU's Lua interpreter (NodeMCU 0.9.5 build 20150318 / Lua 5.1.4 to be specific), you can run commands, and 'save' Lua programs directly to the module's Flash using a USB-Serial converter cable. But, if you'd like, you can skip Lua and go direct to using the Arduino IDE. Once you download the ESP8266 core, you can treat it just like a microcontroller+WiFi board, no other processors needed!

Each order comes with one assembled and tested HUZZAH ESP8266 breakout board, and a stick of 0.1" header that you can solder on and plug the breakout into a breadboard. A soldering iron and solder are required for that, and aren't included. Solderless breadboard also not included. You'll really want a USB-serial cable such as a USB console cable (good for Windows, not suggested for MacOSX users),  FTDI Friend (great for any OS), or FTDI cable (great for any OS)  to upload software to the HUZZAH ESP8266! Our essential tutorial has wiring, pinouts, assembly, downloads, and more!
