pIRkey

Image of Board

The pIRkey adds an IR remote receiver to any computer, laptop, tablet…any computer or device with a USB port that can use a keyboard. This little board slides into any USB A port, and shows up as an every-day USB keyboard. The onboard ATSAMD21 microcontroller listens for IR remote signals and converts them to keypresses, mouse movements, or even USB serial output.

Infrared is a favorite wireless protocol - no antennas, certifications, pairings, passwords, or special tools required. Works everywhere in the world and very intuitive - everyone’s got an IR remote in their home.

The pIRkey is an improvement on Adafruit’s original IRkey product, by adding a p for python. Now with CircuitPython being available for the tiny ATSAMD21E processor, it’s swapped in for the ATtiny85, giving a huge boost in power and a working Python interpreter on board as well. This means it is easy to reprogram, customize or adapt it to whatever Infrared-reading needs you may have.

When you plug it in, the pIRkey shows up as a triple device: USB disk drive to store code, USB serial for debugging and Python interactive command line, and USB keyboard/mouse that can transmit keypresses or mouse movements.

By default it ships with simple example code to read NEC remotes but you can use any remote that has about 38KHz output frequency which is the vast majority of remote controls. CircuitPython makes this all very easy to customize and adapt to your own needs.

CircuitPython 4.0.1

This is the latest stable release of CircuitPython that will work with the pIRkey.

Start here if you are new to CircuitPython.

Release Notes for 4.0.1

CircuitPython 4.0.0-rc.3

This is the latest unstable release of CircuitPython that will work with the pIRkey.

Unstable builds have the latest features but are more likely to have critical bugs.

Release Notes for 4.0.0-rc.3

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for it. They are stored on Amazon S3 by language (some which may be unreleased.) Try them if you want the absolute latest and are feeling risky.

Past Releases

All previous releases are available on GitHub. They are handy for testing but we recommend the latest stable otherwise.
