The bykeeb aka baby yoda keyboard by Sadek Baroudi is a 36-key wireless min-y spacing keyboard, supporting MX, Choc, and Gateron low profile switches.
I'd like to introduce bykeeb (baby yoda keyboard)! […] The switch spacing on this board is what I call min-y standard-x spacing. This is 19mm x 16mm – Sadek.
According to the author, this keyboard is wireless only, meaning you cannot use a Xiao RP2040.
