This is the PurpleTooth Jamboree a full-function board, designed to provide audio bridge support through the A2DP, HFP, and AVRCP Bluetooth Classic profiles. The module is also dual mode which means it can operate as Bluetooth 2.1 or Bluetooth 4.0 (BLE). It includes circuitry for converting single-ended audio inputs and microphones to balanced inputs for the module, and converting the module’s balanced audio output to an amplified single-ended signal suitable for line-input and headphones. The PurpleTooth also includes buttons for pairing and sending audio commands to remote devices, battery charge circuitry, and six-pin serial headers pinned out for connecting to either FTDI basic boards or boards like the Arduino Pro, Pro Mini, and LilyPad.

Each PurpleTooth Jamboree comes standard with a BC127 Bluetooth module, an extremely competent and easy-to-use dual-mode Bluetooth radio. In command mode, any data coming in on the serial port is treated as commands and will be parsed accordingly by the module’s command interpreter. In data mode, any data arriving over the serial port will be directly piped out over the Bluetooth link, assuming that the module is connected to another device using the Serial Port Protocol.

The PurpleTooth is equipped with one Mic in / LINE in 3.5mm jack (with additional 4-pin through-hole mic adapters), one Headphone / LINE out 3.5mm jack (with additional 4-pin through-hole L/R speaker adapters), seven button volume, track, play and pair control, serial to micro and FTDI support, and a USB micro port for power and updating the firmware (you will need a 5V FTDI for serial commands).

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 ADC functionality to the Edison’s I2C bus. The ADS1015 ADC from TI provides a single 12-bit delta-sigma convertor with an analog multiplexer. It can be configured as a four-channel single-ended device or as a two-channel differential device.

The ADC Block has jumpers to allow selection of the I2C slave address among four different options, allowing up to four of these cards to be stacked under one Edison. The sampling rate is not sufficient for audio capture, at 2.2kHz, but it should be adequate for most control applications.

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.

This is a simple board that no one really needs but it sure comes in handy. If you’ve ever tried to hook up an FTDI to something only to realize you need to swap the TX and RX, maybe you could use this board. Sure, you can grab some jumper wires and make your own, but this little crossover board makes it much easier.

The board has a set of headers going in and a set going out. The TX and RX lines are swapped so you can connect it to a Bluetooth Mate and configure it without having to swap the pins coming from your FTDI.

Our Adafruit Bluefruit LE (Bluetooth Smart, Bluetooth Low Energy, Bluetooth 4.0) nRF8001 Breakout allows you to establish an easy to use wireless link between your Arduino and any compatible iOS or Android (4.3+) device. It works by simulating a UART device beneath the surface, sending ASCII data back and forth between the devices, letting you decide what data to send and what to do with it on either end of the connection.

Unlike classic Bluetooth, BLE has no big contracts to sign and no major hoops that you have to jump through to create iOS peripherals that you can legally design and distribute in the App Store, which makes it a great choice compared to classic Bluetooth which had (and still has) a lot of restrictions around it on the iOS platform.

And now that Android also officially supports Bluetooth Low Energy (as of Android 4.3), it's also -- finally! -- a universal communication channel covering the main mobile operating systems people are using today.

Please note! We still manufacture and support the nRF8001 Bluefruit module sold here, but we really recommend going with the fresh new Bluefruit LE nRF51822 based modules, they're much more powerful and thus need less code on the Arduino side, have a lot more capability and flexibility so you can do more, require fewer pins, are overall smaller, can be updated with new firmware and are FCC/CE approved! They come in both UART and SPI interface type (both have same functionality, one just uses serial, one uses SPI)

We can get you started super fast with this BLE module which can act like an 'every day' UART data link (with an RX and TX characteristic). Send and receive data up to 10 meters away, from your Arduino to an iOS device. We've even made it easy to get started with our very own BLE connect app that has a "serial console" for sending/receiving data and also an 'arduino pin i/o control station" to let you set pins on your Arduino to inputs or outputs, high or low logic or even PWM output, as well as read button presses and analog inputs. You can start prototyping your accessory and then use our open source Objective C code to base your new app on!

The nRF8001 is nice in that it is just a BLE 'peripheral' (client) front-end, so you can use any micrcontroller with SPI to drive it. We have example C++ code for Arduino, which you can port to any other microcontroller, but some microcontroller is required - it is not a stand-alone module!

This is a product for ADVANCED USERS - At this time we recommend this product for people who are either OK with using the apps available (Nordic's UART demo or our Bluefruit LE Connect) or are comfortable with writing iOS apps (and can refer to our App repository). We do not have a tutorial for writing your own iOS or Android BLE app at this time, don't worry we're working on one :)

We have a guide to help you setup your nRF8001 Bluetooth Low Energy breakout, and start using some of the sample sketches we provide with it to connect to an iOS or Android device.

We also now have an app for Android users available here!

If you're new to Bluetooth Low Energy, be sure to check out our Introduction to Bluetooth Low Energy learning guide as well!

"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

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

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.

Would you like to add powerful and easy-to-use Bluetooth Low Energy to your robot, art or other electronics project? Heck yeah! With BLE now included in modern smart phones and tablets, its fun to add wireless connectivity. So what you really need is the new Adafruit Bluefruit LE SPI Friend!

The Bluefruit LE SPI Friend makes it easy to add Bluetooth Low Energy connectivity to anything with 4 or 5 GPIO pins. With SPI, you don't have to worry about baud rates, flow control, or giving up a hardware UART port. Connect to your Arduino or other microcontroller using the common four-pin SPI interface (MISO, MOSI, SCK and CS) plus a 5th GPIO pin for interrupts (to let the Arduino know when data or a response is ready).

This multi-function module can do quite a lot! For most people, they'll be very happy to use the standard Nordic UART RX/TX connection profile. In this profile, the Bluefruit acts as a data pipe, that can 'transparently' transmit back and forth from your iOS or Android device. You can use our iOS App or Android App, or write your own to communicate with the UART service.

If you like Serial communication more than SPI, we also have a version that can talk UART

The board is capable of much more than just sending strings over the air!  Thanks to an easy to learn AT command set, you have full control over how the device behaves, including the ability to define and manipulate your own GATT Services and Characteristics, or change the way that the device advertises itself for other Bluetooth Low Energy devices to see. You can also use the AT commands  to query the die temperature, check the battery voltage, and more, check the connection RSSI or MAC address, and tons more. Really, way too long to list here!

Download our free Android/iOS app and you're ready to rock!

Using our Bluefruit iOS App or Android App, you can quickly get your project prototyped by using your iOS or Android phone/tablet as a controller. We have a color picker, quaternion/accelerometer/gyro/magnetometer or location (GPS), and an 8-button control game pad.

You can do a lot more too!

The Bluefruit can also act like an HID Keyboard (for devices that support BLE HID)

Can become a BLE Heart Rate Monitor (a standard profile for BLE) - you just need to add the pulse-detection circuitry

Turn it into a UriBeacon, the Google standard for Bluetooth LE beacons. Just power it and the 'Friend will bleep out a URL to any nearby devices with the UriBeacon app installed.

Built in over-the-air bootloading capability so we can keep you updated with the hottest new firmware. Use any Android or iOS device to get updates and install them!

Why use Adafruit's Module?

There are plenty of BLE modules out there, with varying quality on the HW design as well as the firmware. So why should you go with this one?

One of the biggest advantages of the Adafruit Bluefruit LE family is that we wrote all of the firmware running on the devices ourselves from scratch. We control every line of code that runs on our modules ... and so we aren't at the mercy of any third party vendors who may or may not be interested in keeping their code up to date or catering to our customer's needs.

Because we control everything about the product, we add features that are important to our customers, can solve any issues that do come up without begging any 3rd parties, and we can even change Bluetooth SoCs entirely if the need ever arises!

Check out our tutorial for all of the details that you can dream of!

So it turns out that your XBee based device would work even better as a Bluetooth device… that probably means back to the drawing board, right? Well not anymore! Now you can swap in Bluetooth functionality without a major hardware redesign!

This is a breakout for the BC127 Bluetooth Module. The BC127 is a highly flexible, low power, small form factor Bluetooth Version 4.0 Certified Audio module. This is an ideal module for developers who want to quickly and cost effectively integrate Bluetooth functionality into their products.

The BC127 Breakout board provides basic access to all the pins on the BC127 module, along with a six-pin serial header with the same pinout as the FTDI Basic boards, allowing it to connect to boards like the Arduino Pro, Pro Mini, and LilyPad. It also includes voltage regulation, serial data level shifting circuitry, and support for the built-in battery charge circuitry.

This is the SparkFun BLE Mate 2, an efficient and reliable Bluetooth 4.0 development board. The BLE Mate 2 closely resembles a breakout board, in that nearly every pin on the on-board BC118 module is made available to access. This board is actually a close cousin to our Gold and Silver Bluetooth Mates and functions in a very similar way but, as the name implies, operates as Bluetooth Low Energy instead of Bluetooth 2.0.

The BLE Mate 2 offers a six-pin header on the end opposite the BC118 module which is used as a “host” serial pinout, the same as that on the FTDI Basic boards, which allows the BLE Mate 2 to be connected directly to any device with a matching header, such as the SparkFun Arduino Pro and Pro Mini. Coupled with the FTDI SmartBasic, you can even develop your code without having to swap cables! The board has built-in level translation, so it can be used with boards of higher voltage than the 3.3V default used by the BC118.

Each BLE Mate 2 offers BC118 module that is capable of accepting and transmitting via the UART at 9600bps (default) with a frequency band of 2,402 MHz to 2,480 MHz.

The SparkFun BLE Mate 2 only supports Bluetooth 4.0; it won’t connect to older devices. It’s also worth noting that BLE does not support a Serial Port Protocol as older versions of Bluetooth did; that makes interoperability between BLE dongles, devices, and modules harder than with Bluetooth Classic.

The BlueSMiRF Silver is the latest Bluetooth wireless serial cable replacement from SparkFun Electronics! This version of the popular BlueSMiRF uses the RN-42 module which has a bit less range than the RN-41 module used in the BlueSMiRF Gold. These modems work as a serial (RX/TX) pipe. Any serial stream from 2400 to 115200bps can be passed seamlessly from your computer to your target.

The remote unit can be powered from 3.3V up to 6V for easy battery attachment. All signal pins on the remote unit are 3V-6V tolerant. No level shifting is required. Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit if you need to attach this to a computer.

Unit comes without a connector. Please see related male and female pins below.

The MaKey MaKey is really cool, but wouldn’t it be cooler if it wasn’t tethered to your computer? There’s only one way to find out: Go wireless.

Our Bluetooth & LiPo Add-On for MaKey MaKey frees your MaKey invention from the bonds of USB wired connection. Data is passed over a Bluetooth HID connection to your Bluetooth enabled computer which will recognize it as a Bluetooth wireless keyboard. Power is handled through a 2-pin JST connector, simply connect any of our 3.7V lithium-polymer batteries. If the MaKey MaKey is plugged in using USB, the Bluetooth & LiPo Add-On will use that source to charge any connected LiPo battery!

To get this thing up and running, you will need to upload some special code to your MaKey MaKey so some Arduino knowledge is recommended. Check out the wiki below for more information.

Note: This Add-On board does not include a LiPo battery, check the related items below for compatible batteries! If your computer doesn’t have Bluetooth, no worries, check out the Bluetooth USB Module in the related items!

The Bluetooth Mate Gold is very similar to our BlueSMiRF modem, but it is designed specifically to be used with our Arduino Pros and LilyPad Arduinos. These modems work as a serial (RX/TX) pipe, and are a great wireless replacement for serial cables. Any serial stream from 2400 to 115200bps can be passed seamlessly from your computer to your target. We’ve tested these units successfully over open air at 350ft (106m)!

Bluetooth Mate has the same pin out as the FTDI Basic, and is meant to plug directly into an Arduino Pro, Pro Mini, or LilyPad Mainboard. Because we’ve arranged the pins to do this, you cannot directly plug the Bluetooth Mate to an FTDI Basic board (you’ll have to swap TX and RX).

This unit ships with an RN-41 class 1 bluetooth module, a very easy-to-use and well documented bluetooth module. Make sure you check out the datasheet and command set links below. If you don’t need the extra range, check out the Bluetooth Mate Silver which uses a Class 2 module which has less range.

The Bluetooth Mate has on-board voltage regulators, so it can be powered from any 3.3 to 6VDC power supply. We’ve got level shifting all set up so the RX and TX pins on the remote unit are 3-6VDC tolerant. Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit if you need to attach this to a computer.

Unit comes without a connector; if you want to connect it to an Arduino Pro, we’d suggest the 6-pin right-angle female header.

Note: If you are looking for the ability to use the FTDI directly with your Bluetooth Mate check out our Crossover Breakout for FTDI!

Note: The hardware reset pin of the RN-41 module is broken out on the bottom side of the board. This pin is mislabeled as ‘PIO6’, it is actually PIO4. Should you need to reset the Mate, pull this pin high upon power-up, and then toggle it 3 times.

The RN-42 is perfect for short range, battery powered applications. The RN-42 uses only 26uA in sleep mode while still being discoverable and connectable. Multiple user configurable power modes allow the user to dial in the lowest power profile for a given application. If you need longer range, check out the Bluetooth Mate Gold.
