Staggered Columns Split Budget AF 40% ergonomic keyboard
The SCSBAF40 keyboard is 40% Staggered Columns Split Budget AF ergonomic keyboard. Heavly inspired by REVIUNG34 and Squiggle.
Project goals: - single arduino, simple design - split - staggered columns with dimensions fitting my fingers length - easy to build with easily obtainable and cheap parts - all software written in arduino IDE - minimum 40 keys (that's main difference between this project and squiggle or reviung)
