# Clicky devboard

## [[JOURNAL]](https://github.com/espcaa/clicky-devboard/blob/main/JOURNAL.md) - [[BOM]](https://github.com/espcaa/clicky-devboard/blob/main/kicad/production/bom.csv) - [[KICAD FILES]](https://github.com/espcaa/clicky-devboard/tree/main/kicad)

This is a devboard based on the RP2350 chip (the rp2040's successor) with three mechanical switches, with every gpio exposed on pin headers + extras like 3v3 and vbus. It was entirely designed in Kicad and everything is open source! 4 layer board that can be manufactured with normal jlcpcb tolerances.\

you can download everything in the [kicad/ folder](https://github.com/espcaa/clicky-devboard/tree/main/kicad)

## Notes

- there's a resistor missing for the usb-c, so it only works in one orientation :(
