Creators! Feel free to tip me off about your keyboard related projects to bring them to 100K readers.

The Zerosprey42 keyboard is a 42-key, wired, low-pro (Choc v1) hotswap monoblock split with a daughterboard rather than an onboard MCU – remixed and shared by Beekeeb's Leo.

It balances between portability and ergonomics with a sleek 3D printed travel case. This is a remix of ebastler‘s Osprey with a low cost yet powerful RP2040-Zero – Leo.

(For a case, check out ebastler's Osprey.)
