Summary

Simple macro keyboard for MiSTer FPGA hardware replicator.
Basic control keys and the ability to save a screenshot.
I used MX cherry keys desoldered from electronic waste.

For Raspberry Pi Pico, but any similar microcontroller that supports the Kyeboard.h library in ArduinoIDE can be used.
