This is a 60% ANSI keyboard that you can build yourself from the ground up. This repository contains the PCB (Gerbers) files, the firmware and the 3D printable files that you need to complete the build. The soldering process is easy and can be done by anybody with a little bit of experience.
To flash the first time I connect an ST-Link to the debug pins, flash a QMK firmware and from there on I can just use the QMK to DFU feature to flash via USB.
In the 3D file's folder you can find the printable plate that supports plate mounted stabilizers. This PCB doesn't support PCB mounted stabs.
In the Firmware folder in this repo you can find the files to compile the QMK-based firmware for the board. Inside the layout folder you can find the default layout, you can add a different one or modify the default one. The default layout is as pictured below.
When the key "L1" is pressed (and kept down) it will switch to the alternative layer (the gray keys). The keyboard will go back to the default layer as soon as L1 is released.
