ButtonBlaster is a compact 48-key keypad based on the Orpheus Pico microcontroller and designed to work with the KMK firmware. The project was inspired by an ergonomic keyboard shown in a video by Joe Scotto. The PCB was custom-designed and paired with a 3D-printed case. It uses Gateron mechanical switches and discrete diodes.
