Introducing my Macropad! I used a Heltec Wifi Kit V3 and Adafruit NeoKey 5x6 Ortho Snap-Apart to create a sleek, functional keypad with Cherry MX keyswitches. The keypad features a nice slope, a cutout for a USB-C battery charger, and enough space for a battery. To make it easy to turn the device on and off, I added a switch. The backplate is held in place by 4mm magnets for easy access to the internals.

If you have any suggestions for improving the code or the keypad itself, please don't hesitate to contact me.
