Want one?

All production files you need to build your own board can be found here.

The case has no bottom and ends right below the HS Sockets. You may either it as is, but preferably use some 2-3mm self-adhesive neopren on the whole pcb. The case may be hard to print on a FDM Printer, so maybe use a service to print it in resin. The cases on the picture are both made from white resin and were spraypainted.

It's advised to get the pcb's preassembled, since the MCU is really hard to solder per hand. Pick and place as well as BOM files can be found in the prod folder.

Apart from the pcb and optionally a case you need:

• 30-36 hotswap sockets
• 30-36 of your favourite switches

just solder the HS Socket, plug in your switches and you should be good to go.

firmware

firmware configs for qmk and vial can be found in the [firmware folder].

The first time the pcb is plugged in, the bootloader will provide a drive to upload the firmware file.
