A 36-key, ultra-compact, foldable, ergonomic keyboard. It's designed to be as small as possible while remaining comfortable for typing. When folded, the keyboard measures only 76x115x12mm and weighs 115g.
Warning
The current prototypes are functional but not perfect. Soldering the switches on a hot plate is extremely challenging. Be prepared for multiple attempts and have spare switches on hand.
The hardware is designed in the KiCad EDA suite. The PCB is designed with components available from the JLCPCB assembly service. The power supply and MCU module selection are heavily inspired by the nRFMicro project.
The firmware is based on the ZMK project and uses a layout based on Miryoku. The source code is available at https://github.com/kumekay/miryoku_zmk.
