Open-source split keyboard with analog Hall-effect switches. Each half has 32 TMR2615F sensors and an AT32F405, and the two halves connect over USB-C. The firmware is our own, built on the Artery BSP and TinyUSB. It shows up as a boot keyboard plus a raw HID interface for configuration. KiCad files are in hw/, firmware in fw/.
