Scaffold
About the Scaffold PCB
Scaffold is an open source PCB design by choubbikeyboards, published on GitHub under the Unlicense license. It is a 2-layer board measuring 242 × 155 mm, with 32 components from 10 distinct parts.
Other key parts include the Pro_Micro. By type, the board carries 2 ICs, 2 switches and 2 LEDs.
It belongs with the keyboards designs in this gallery.
From the project
Modular split keyboard powered by QMK, with joysticks for mouse/scrollwheel emulation
This keyboard is inspired by many others, among which the Ferris, the Kyria, the Dactyl Manuform, and others. The major contribution of this project is the method of using PCB for simultaneous structural support and electrical wiring of individual keys.
This is still pretty much a prototype. The files I provide here have not yet been made into a PCB, although a previous version with minor changes has been tested successfully for some parts, and not so much for others. Software side is not too advanced either, and you'll have to write your own QMK keymap.c file, as I didn't write a basic…
