Open source single key USB keyboard

[Coreda]

Article I came across via Hackaday. Open sourced on Github (links in blog). Maker previously created a three key version.



Have seen a few like this posted here in the past but thought this was a cool open source project worth sharing.

That's very interesting.
That MCU is cheap and has 16 GPIO with 2 PWMs and runs at 16 MHz on its internal oscillator.
I'm glad someone released an opensource firmware for it, not that I'm unhappy with the m32u4 but it's always nice to have alternatives, especially for that price.

Thanks for posting it.
