  • 8-core Parallax Microcontroller on-board
  • 30 IO pins broken out, serial data/programming connection to Pi
  • 20 Pi pins broken out for communications/ease of access
  • 170pt breadboard for experimentation
  • Python quick start library with PWM/Servo and GPIO libraries

Getting started

For instant-gratification you can try the Propeller HAT IO libraries:

You'll need Propeller IDE to start programming your Propeller HAT:

Propeller IDE Installation

As always, we've made it super-easy for you to get all the software you need with a nifty one-line installer. To run it fire up Terminal which you'll find in Menu -> Accessories -> Terminal on your Raspberry Pi desktop like so:

Finding the terminal

In the new terminal window type:

curl -sS | bash

This will install a fairly recent version of the Propeller IDE but if you'd like you can head over to and grab the latest version of Propeller IDE for the Raspberry Pi, which may be newer than the one installed by the one-line installer.

Propeller IDE download

It's easier if you grab the right URL, and use the wget command on your Raspberry Pi to download it. For example:


Once downloaded, you can install it with:

sudo dpkg -i propelleride-0.36.7-armhf.deb
