KBD.news Published August 7, 2022
Kretsträd , which I guess means "circuitry" in Norwegian, is a wireless split by jw aka wj-zhe .
The starting point for the design was the Sweep, the author's first build, but columns under litter finger "was far too low to reach". Besides, he wanted a wireless one to use on multiple devices.
Specs
34 keys per half
Seeeduino XIAO BLE controller
stacked case with all plates made from acrylic
LIR2032 coin cells should work in the author's opinion for 4-5 days
