Notes
- Designed around the Raspberry Pi RP2040 microcontroller.
- Uses a 12MHz external crystal and Winbond SPI flash.
- USB Type-C connector footprint is compatible with HRO TYPE-C-31-M-12.
- All resistors and capacitors use 0402 footprints unless otherwise noted.
- Some LCSC parts may become unavailable over time; equivalent parts with matching value, package, and electrical specifications may be substituted.

Questions
How big is the Devboard PCB?
It measures 21 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Devboard use?
35 parts, built around the RP2040, W25Q16JVUXIQ and SK6812MINI-E. 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 Devboard KiCad files?
From the AYUSH-pro-grammer/devboard repository on GitHub, at the commit this page was made from: the board is kicad/devboard.kicad_pcb and its schematic kicad/devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Devboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask AYUSH-pro-grammer before reusing the design.
