12 Key Macro Keyboard
This is a cute little keypad I designed to showcase how to integrate an ATMega32u4 directly onto your keyboard PCB. It is compatible with Cherry, Alps, and Chocc style keys and has per-key backlighting with SK6812 mini-e LEDs. It also has some 3535 SK6812 on the back to give a nice backlight when used with a clear case. Watch the video and consult the linked eagle files for more info:
