The unibody Ch55p34 by Alex Miller uses the CH552T MCU, and it runs on FAK firmware.

Creators! Feel free to tip me off about your keyboard related projects to bring them to 100K readers.

Alex Miller aka keyboarddweebs is back with Ch55p34, a monoblock splits board using the relatively cheap CH552T MCU and FAK firmware – a combo popularized by Richard Goulter's boards.

I just created a new keyboard based on the ch552t chip. Runs on FAK firmware. I named it the Ch55p34 because it's "Ch55p" – Alex.


  • 34 keys (3x5+2)
  • hotswap, MX
  • CH552T MCU
  • FAK firmware

Custom low-pro mounting :)

You can use the Ch55p34 without a case, or you can use the 3d printable case and plate provided in the repo.

I forgot to add mounting holes, and because of this, I had to find a way to mount the plate to the case. […] Four m2x10mm screws hold the plate in place. From the side. An unintended side effect is that it is about 7 mm thinner than any other keyboard I've made with a case. I may do this for the rest of my keyboards! – Alex.



The GitHub repo has everything that you need to make one on e.g. jlcpcb. BOM and PIP folders and files:
