Questions
How big is the Pdaltmode PCB?
It measures 50 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Pdaltmode use?
88 parts, built around the CH32X035G8U6, TLV62569DBV, CBTL02043ABQ and CH217K. 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 Pdaltmode KiCad files?
From the AnterCreeper/pdaltmode repository on GitHub, at the commit this page was made from: the board is EVB/pdaltmode.kicad_pcb and its schematic EVB/cover.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pdaltmode design in my own project?
Its repository publishes it under the LGPL-2.1 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
