34-key split ergonomic keyboard with trackpoint. Per-half XIAO nRF52840 Plus, BLE split, ZMK firmware.
- Daily driver: breakout-board prototype, Sprintek AIO trackpoint on the
left half. Pinned at the
proto/breakout-v1tag. - Next board: hand-laid KiCad PCB under
pcb/, 34 keys (5×3 alphas + 2 thumbs per half), Choc V2 hotswap. - ADS1220 strain-gauge trackpoint: firmware bench-proven (HID mouse,
radial deadzone, click-to-wake via input-processor-ping) — pinned at
bench/ads1220. Currently being hand-laid into the PCB.
Host <--BLE-- Left (central + trackpoint) <--BLE-- Right (peripheral)
When the trackpoint moves, the mouse layer auto-activates for ~1 s after the last movement.
