Creators! Feel free to tip me off about your keyboard related projects to bring them to 120K readers.

Tien Pham aka phamfoo shared a hotswap ortho board: the Form Zero. The project aimed to provide a keyboard that looks nice while also including some features that you'd find in custom mechanical keyboards: gasket-mounted, hotswap PCB, clean and minimal design.

I wanted to try an ortholinear board but couldn't find one I liked, so I made one – phamfoo.

The PCB supports 2 layouts. For the bottom row, you can either go with one or two 2u keys in the middle.


The top case covers most of the board, you can swap it out for a different color.


  • 5x12 ortho (58-59 keys): 2x2u or 1u-2u-1u bottom
  • hotswap (only)
  • gasket mounted
  • RP2040 Zero
  • USB daughterboard
  • Resin/FDM 3D printed case

To make this work with an off-the-shelf microcontroller (the RP2040 Zero), there's a carrier board connected to the main PCB with flat cables.


The plate, resin 3D printed case, and PCBs came from JLCPCB.
