Pimoroni Propeller Hat

Propeller HAT will get you flying in the world of microcontrollers; whether you’re just learning the ropes, or using it as an integral part of your home automation project.

We’ve brought the much adored Parallax Propeller microcontroller to the Raspberry Pi in an experimentation-friendly HAT format that includes a mini breadboard for prototyping and breaks out a whole array of signals from both Pi and Propeller.

Ideal for servo twiddling, robot building, IO-expanding, VGA driving, or rockin’ to classic tunes with sound chip emulators like SIDcog. Parallax’s Object Exchange is packed with code examples and libraries: http://obex.parallax.com/

Features:

Stonkin’ 8-Core Micro handles menial IO tasks for your Pi

30 general purpose IO pins controllable by any of the 8 cores

Easy to program using the Pi-compatible Propeller IDE and SPIN language

On-board 170pt breadboard for hosting your experiments

Breaks out Pi SPI, I2C and 15 other pins

Fully open-source hardware, right down to the microcontroller!

Supplied as a kit with female headers

Supplied as a kit - Male or female headers, it's a tough choice and there's a good case for both. We've bundled Propeller HAT with a 170pt breadboard and female headers, but left them un-soldered and un-stuck so you can choose what fits you best. That does mean, however, that soldering is required!

Built around the Parallax Propeller - Propeller HAT hosts the powerful 8-core Propeller microcontroller from Parallax. It connects it to your Pi’s serial port for programming, and breaking out its 30 remaining pins for general IO use.

Fully programmable on the Pi - All the tools you need to program Propeller HAT will run on the Raspberry Pi. From Propeller IDE, the software you need to write SPIN code, to OpenSpin, the compiler, and p1load, the loader.

Python IO library - We’ve created a collection of Python IO library examples. Just import them into Python and instantly transform your Propeller HAT into a 30-pin IO expander or PWM driver.

Learn microcontroller and multi-core programming - using SPIN, the native language of the Propeller, you can learn how to make a microcontroller do your bidding. We've written step-by-step tutorials to get you acquainted with the basics.

Fully open-source - The Propeller is open source; from the tools used to program it, right down to the code describing the hardware itself: http://www.parallax.com/microcontrollers/propeller-1-open-source

SmartMatrix SmartLED Shield (V4) for Teensy 3

So you have a Teensy and a RGB LED Matrix Panel and you want an easy way to add graphics to your matrix without having to toss aside your Teensy or do too much soldering. Enter the SmartMatrix SmartLED Shield (V4) for Teensy 3.2, 3.5, or 3.6 (not the Teensy LC)!

The SmartLED Shield gives you an easy way to connect up a Teensy 3.2, Teensy 3.5, or Teensy 3.6 to one of our RGB LED Matrix Panels. The example sketches included with the SmartMatrix Library will get you started quickly displaying graphics, patterns, or even animated GIFs from a microSD card on your panel.

Features

Shield is fully assembled, no soldering required (besides adding pins to the Teensy)

HUB75 pinout, connects to panel directly or using panel's ribbon cable

5V level shifters for better compatibility with 5V panels

Support for driving Dotstar/APA102 LEDs in parallel with the LED panel, connects directly to 4-pin JST SM cable on Dotstar LEDs, or use the included cable

Expansion rows for main Teensy pins, making signals available for prototyping

Teensy is easily removed from the shield

Note: compared to previous versions of the SmartMatrix Shield, the microSD card slot was removed, as it is redundant when combined with the Teensy 3.5/3.6

The shield brings the 13 I/O signals needed to drive the panel out to a connector that matches the pinout on the panel, and brings the rest of the I/O signals out to convenient expansion headers.  The board includes pre-soldered 5V level shifters.

It's a great board for easily expanding your Teensy's capabilities. You'll also need to program in your Teensy with the SmartMatrix code available on the project website.

Assembled Terminal Block Breakout FeatherWing for all Feathers

The Terminal Block Breakout FeatherWing kit is like the Golden Eagle of prototyping FeatherWings (eg. majestic, powerful, good-looking). To start, you get a nice prototyping area underneath your Feather, with extra pads for ground, 3.3V and SDA/SCL. Not one to stop there, we expanded the PCB out to 2" x 2.5" with 3.5mm pitch terminal blocks down each side. There's also four mounting holes so you can attach the breakout to your enclosure or project.

This product works with all our Feathers! The terminal blocks allow you to connect to any of the external Feather pins, great for wiring temporary or permanent installations. We also give you a few extra terminal block pins for ground and 3.3V connections since those are so useful.

Finally, there's a slide switch, which connects the EN pin to ground when in the 'off' position, cutting off the 3.3V regulator. Note that the FONA Feather uses both VBat and 3.3V as power supplies so you wont be able to fully turn off the FONA Feather with this switch.

Note: As of Thursday, December 15th 2016, this product now comes fully assembled! Plug in your Feather and you're ready to go immediately.

Also, the terminal blocks included with your product may be blue or black.

FeatherWing Doubler - Prototyping Add-on For All Feather Boards

This is the FeatherWing Doubler - a prototyping add-on and more for all Feather boards. This is similar to our FeatherWing Proto except there are two! The magic of the Doubler comes when stacking a Feather and another board on top of the Doubler so you can work with both boards simultaneously side-by-side! In addition to the board the Doubler comes with:

1 Doubler PCB

1 set Feather Stacking Headers

1 set Feather Female Headers

The Doubler, like the Proto, has a duplicate breakout for each pin on a Feather, as well as a bunch of plain grid proto holes. Also, the two sets of pins are cross connected and for GND and 3.3V, we give you a full strip of connected pads.

You'll need to solder on the female headers or stacking headers however you like, the Doubler comes as a mini kit!

Bus Pirate - BPv3.6 - v3.6

Interfacing a new microchip can be a hassle. Breadboarding a circuit, writing code, hauling out the programmer, or maybe even prototyping a PCB. We never seem to get it right on the first try.

The 'Bus Pirate' is a universal bus interface that talks to most chips from a PC serial terminal, eliminating a ton of early prototyping effort when working with new or unknown chips. Many serial protocols are supported at 0-5.5volts, more can be added.

Adafruit is the official US distributor of Ian Lesnet's Bus Pirate, each purchase directly supports Dangerous Prototypes! You may also want to pick up a probe set.

FeatherWing Proto - Prototyping Add-on For All Feather Boards

A Feather board without ambition is a Feather board without FeatherWings!

This is the FeatherWing Proto - a prototyping add-on for all Feather boards. Using our Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top or bottom of your Feather board and let the board take flight!

This has a duplicate breakout for each pin on a Feather, as well as a bunch of plain grid proto holes. For GND and 3.3V, we give you a strip of connected pads. There's plenty of room for buttons, indicator LEDs, or anything for your portable project. The FeatherWing Proto makes an ideal partner for any of our Feather boards.

SparkFun MicroView - USB Programmer

The MicroView is the first chip-sized Arduino compatible module that lets you see what your Arduino is thinking using a built-in OLED display. This USB programmer connects directly to the MicroView and lets you not only program the module, but use it to interface with your computer, Rapsberry Pi, or other USB device. The programmer has both male and female headers which allow it to be plugged into a MicroView module and a breadboard at the same time, making prototyping quick and easy.

If you want to learn more about the MicroView, check out the Kickstarter page.

Note: A MicroView OLED Arduino Module is NOT included with this USB Programmer. Check the Recommended Products section below to find one!
