Bakeneko40 is an open source AVR/Arduino PCB design by HorseyMask: a 2-layer, 266.7 × 76.2 mm board with 115 components (19 distinct parts). It is built around the ATMEGA32U2-MU, SRV05-4. Filed under keyboards.

40% verison of the bakenkeo40 keyboard by kkatano.

PCB is still in testing and unconfirmed to work, but otherwise project is mostly done.

Case is a bit too big for plate and pcb. Either edit case or use foam between pcb and plate to allow more room for oring.
