OSFRD stands for OpenStickFirmware Reference Design. This is a mini all-keys controller with a custom printed circuit board (PCB). It sports 12 Kailh BOX red linear switches with influences from the classic Sega 2P layout. They are mounted on Kailh hot-swap sockets that can be swapped with any standard switches in the Cherry MX style. As for the six auxiliary buttons, they are mounted at a right angle in the back to avoid accidental presses. The icing on the cake is that the face keys have RGB LEDs, and there are four additional LEDs up top.

This entire apparatus is powered by a Raspberry Pi Pico that runs OpenStickFirmware. Also, there is a 20 pin header that is compatible with PCBs like the Brook Universal Fighting Board (UFB). As for the material of the case, it is clear acrylic.

At present, the OSFRD is in its first phase, and its current prototype form needs to be purchased to fund the second round of units, which partially includes better optimization for Brook product support. Soon, the OSFRD should be able to support the Nintendo Switch and Xbox 360 as well.

There have already been successful tests on:

  • Street Fighter V
  • Tekken 7
  • Guilty Gear Strive
