This is a nine-key macropad with an OLED and two LEDs.
I will make this using:
- 9x Cherry MX Switches
- 9x DSA Keycaps
- 9x 1N4148 DO-35 Diodes
- 2x SK6812MINI-E LEDs
- 1x 0.91" 128x32 OLED Display
- 1x XIAO RP2040
- 1x Case (2 printed parts)

I made this to delve into the world of hardware for the first time. I've never made something like this before. I am quite excited to build it and use it.
