I have followed the Build-A-Devboard Guide by @KaiPereira on HackClub Macondo (https://macondo.hackclub.com/docs/build-a-devboard)
This project uses pre assebmled PCBs if u want to build on your own the mentioned guide should be enough.

Questions
How big is the Devboard PCB?
It measures 30.8 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Devboard use?
33 parts, built around the RP2040 and W25Q128JVSIQ. 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 suhaan2485/SB-Devboard repository on GitHub, at the commit this page was made from: the board is KiCad Files/Devboard.kicad_pcb and its schematic KiCad Files/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 suhaan2485 before reusing the design.
