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

After sharing his Pica40 v2 and PicaChoc36, Evgenii Vilkov aka zzeneg is back with Pica40 v2.1.

Just a small incremental update to my Pica40 keyboard – zzeneg.


  • TRRS support added so it can be used instead of USB-C if you prefer it (or just don't want to solder USB-C connectors).
  • Rotary encoder can be on any side, not only left one as before.
  • 3D printed case has a better shape, has more battery space and there is also a thin version now, as low as regular MX can go – thanks to the bottom plate with cutouts and a rubber sheet instead of usual legs. Top plate is only 9.3mm from table.
