Questions
How big is the Custom Development Board PCB?
It measures 21 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Custom Development Board use?
42 parts, built around the RP2040, W25Q128JVSIQ and WS2812B. 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 Custom Development Board KiCad files?
From the maraulsav/PISTAR repository on GitHub, at the commit this page was made from: the board is KICAD/Custom Development Board.kicad_pcb and its schematic KICAD/Custom Development Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Custom Development Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask maraulsav before reusing the design.
