Crkbd-4x6
About the Crkbd-4x6 PCB
Crkbd-4x6 is an open source PCB design by mcweihing, published on GitHub. It is a 2-layer board measuring 134.3 × 110.4 mm, with 72 components from 12 distinct parts.
Other key parts include the ProMicro. By type, the board carries 27 switches, 27 diodes, 9 jumpers, 5 connectors, 2 resistors and 1 IC.
It belongs with the keyboards designs in this gallery.
From the project
An adaptation of the crkbd keyboard. It contains a 4x6 matrix and three thumb keys. It's also MX and Choc hotswappable.

All of the KiCad files needed to print the pcb are included. I know that the gerber files included are enough to print through JLCPCB.
I have dxf files to get plates made for the pcb's, but I won't have access to that computer for at least a week or two. Same with QMK.
