From the project
A highly portable split keyboard focused on feeling and sound.
An ergonomic split keyboard PCB with an integrated capacitive trackpad, Sharp Memory Display, and speaker. Designed around Kailh Choc low-profile switches and styled after Nothing.
Orthus is a 6×5 ortholinear split — two mirrored halves, one with the alpha cluster (QWERT/ASDFG/ZXCV) and a number row (1–5), the other with the right-hand alphas, symbols, and a numpad row. Each half carries:
