Clicky devboard

[JOURNAL] - [BOM] - [KICAD FILES]

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.

• RP2350
• 3x Cherry MX switches
• Recommended abracon crystal & inductors
• AP63203WU-7 for the 5v to 3v3 conversion
• 1x23 pin headers
• W25Q64JVSSIQ_C179171 chip for the flash (64mb)
• a usb-c connector
