Sofle RGB V3 Hotswap Split Ergo 50% Keyboard Kit
Designed by Dane Evans based on the original Sofle Keyboard by Josef Adamcik (GitHub repository). Build guide here (does not mention the power switches that are mounted on the top of the PCB on each side).
Modified by 42. Keebs with larger pinky stagger (same as on Sofle V2), power switches and a battery headers.
Please note, be careful when soldering the RGB LED modules. Due to the way the PCBs were manufactured (vias not covered with solder mask), a solder bridge could form from one of the RGB LED pads to a via, causing a short on a data line. If that happens, adding flux helps greatly in removing the solder bridge.
