Pseudonymous developer Matias N. is working on a ergonomic split keyboard design featuring a clever mirrored PCB and powered by the Raspberry Pi Pico or pin-compatible alternative.
"Say hello to [the] split Goji Keeb, based on Raspberry_Pi Pico and Lily58 Pro design," Matias writes of the project's unveiling. "[The] PCB is reversible and supports Cherry MX/Kailh Choc switches and sockets. It is designed to support [the] Pimoroni Display Pack as optional add-on ([with] custom add-ons to be designed later)."
The keyboard is a fully-split ergonomic design, where the boards to be used with the left and right hand are physically separate devices. There's only one PCB, however: The "reversible" design means that the left-hand and right-hand boards are identical, with the right-hand board simply flipped upside-down and the components mounted on the opposite side to its sinister companion.
The board is designed to be powered by a Raspberry Pi Pico microcontroller, though pin-compatible alternatives should also be supported. The PCB's design also includes a broken-out debug port, and a 3.5mm jack that serves to carry communication signals from the left-hand board to the right-hand board and vice versa.
Matais has not yet shared design files for the Goji Keeb, with more information available on the project's Twitter thread.
