Questions
How big is the Udong PCB?
It measures 280 × 150 mm and has 4 copper layers, 1 mm thick.
What parts does the Udong use?
113 parts, built around the RP2040, W25Q128JVSIQ, CD4051BM96 and USBLC6-2SC6. 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 Udong KiCad files?
From the palthedog/Udong repository on GitHub, at the commit this page was made from: the board is ecad/mainboard/mainboard.kicad_pcb and its schematic ecad/analog_switch_tester/analog_switch_tester/analog_switch_tester.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Udong design in my own project?
Its repository states no licence, so its author keeps all rights: ask palthedog before reusing the design.
