Help: Flashing Leaf PCB


Hi Keyboard Folks! I’m in the process of building my Leaf from Foxlabs and I’m SUPER excited. I’m a bit stuck on flashing the board - there aren’t any instructions that I can find online. I tried asking in the keebs Discord, but got no responses.

Can anyone point me in the right direction?

If there isn’t any documentation I can look at, there are two questions I have:
What firmware can I use to flash the PCB? I tried QMK, but there isn’t an entry for the pcb.
What is the command to put the PCB in boot mode? (The PCB doesn’t have a manual boot switch)

Many thanks in advance


Based on the GB thread on geekhack the PCB can be programmed using BMC (Bootmapper Client). I think you can get them at
