The YMDK "Bface" PCB


A 60% keyboard that runs ps2avrgb natively and fits the popular GH60 form factor. Another "bfake" or clone of the original B.face PCB by Winkeyless. This PCB has slightly different switch matrix than the origninal B.face, and is also different than the bfake. It commonly comes as the PCB in 60% keyboard kits sold by YMDK on Aliexpress.

Keyboard Maintainer: QMK Community
Hardware Supported: White Bface Mini USB PCB with no RGB.
Hardware Availability: Shenzhen YMD Tech Co. (YMDK) on Aliexpress

Make example for this keyboard (after setting up your build environment):

make ymdk/bface:default


ps2avr(GB) boards use an atmega32a microcontroller and a different bootloader. It is not flashable using the regular QMK methods.

This board has a pair of jumper holes on the left edge of the PCB marked "Jb", near TAB and CAPS LOCK. If you short the contacts with tweezers or wire the board will enter into the bootloader and you can flash it.


  1. Download HIDBootFlash.
  2. Place your keyboard into reset.
  3. Press the Find Device button and ensure that your keyboard is found.
  4. Press the Open .hex File button and locate the .hex file you created.
  5. Press the Flash Device button and wait for the process to complete.


  1. Install homebrew by typing the following:

    /usr/bin/ruby -e "$(curl -fsSL"
  2. Install crosspack-avr.

    brew cask install crosspack-avr
  3. Install the following packages:

    brew install python
    pip3 install pyusb
    brew install --HEAD`
  4. Place your keyboard into reset by shorting the jumper on the left edge of the PCB..

  5. Flash the board by typing bootloadHID -r followed by the path to your .hex file.

Another method for Mac or Linux: After installing bootloadHID, you can use the ./util/ program included in QMK. You will need to have python and the pyusb library installed.

Then you can run this to compile the firmware and flash the board without using the jumper:

make ymdk/bface:default:program
