Specs
Minor derivated work of ezxzeng's Hector36 keyboard, now with RP2040 zero and TRRS!
Build guide
WIP, but it should be straightforward. Maybe checkout uploaded images.
BOM:
- 2 x PCB (reversible)
- 2 x TRRS socket (PJ320A)
- 2 x RP2040 Zero (no pins required, SMD)
- 36 x MX hotswap socket or variants
In case you are going sandwich cases like me:
- 10 x M2 bolt (length 6 mm)
- 10 x M2 nut (diameter 3 mm)
- 10 x M2 standoff (height 7mm - flexible)
- maybe 8-10 bumpons
Tips:
- Jump at the back
- Use 90 degree TRRS jack, and 90 degree usb c cable if possible
- due to weird locations of TRRS. It may be fixed in the future
With these being said, it could be the most accessible way to try a splayed keyboard / totem layout!

Questions
How big is the Hectrrs36 PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hectrrs36 use?
30 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Hectrrs36 KiCad files?
From the Hanthebot/hectrrs36 repository on GitHub, at the commit this page was made from: the board is kicad/board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hectrrs36 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Hanthebot before reusing the design.
