USB HID Macropad built with Seeeduino Xiao & CircuitPython #CircuitPython @seeedstudio @awarburton

Andy Warburton builds an 8 key USB keypad using the Seeeduino Xiao microcontroller programmed in CircuitPython:

I recently got into Mechanical Keyboards and thought it would be fun to build my own 8 key mechanical macropad. The process is pretty easy and made even easier with the addition of the Seeeduino Xiao which is super cheap and has enough inputs to create a decent sized keypad without the complexities of figuring out how to code a matrix (which if you feel like doing you could create a pad of up to 25 keys with this tiny device!).

The enclosure is 3D printed. Andy has a full separate guide on installing CircuitPython on the microcontroller. CircuitPython has a plethora of device libraries to interface with hardware including one to act as a keyboard via USB to a host computer.

See the entire post and code on Andy’s Website.
