I use a 36 key Chocofi keyboard with a Sprintek SK8707-01 trackpoint, made wireless with nice!nano's.
This repo is where I keep my ZMK firmware as well as my Karabiner Elements setup, and also the files to print the keyboard case & key caps. Since I like having all my keybindings available on my laptop's built-in keyboard as well, most of the interesting stuff is implemented with Karabiner rather than ZMK.
