Goose 38-key split wireless keyboard

Goose is a keyboard built with the help of Ergogen. This means that it's really simple to edit /config.yaml and generate your own design, stagger and splay. The KiCad PCBs are located in pcb/ and contains the pcb, plate and bottom boards. Use them to either manufacture directly or take leads from how I routed the pcb if you create your own.

Description

Wireless 38-key split and reversible keyboard with two rotary encoders, no support for button/press on these. Plate is optional, but I'm using 3-pin switches which does almost make plates mandatory. Batteries soldered directly to PCB, bought batteries with protection against shorts. All PCBs are reversible.

Stagger and splay according to my hands, helped by Ergopad. Artwork generated with Midjourney AI. Not really gooses but goose-like? :D
