Questions
How big is the 326pcb PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 326pcb use?
47 parts, built around the ATSAM4S8BA-AU, ESP32-WROOM-32E and LDL1117S30R. 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 326pcb KiCad files?
From the 04jj/326pcb repository on GitHub, at the commit this page was made from: the board is 326pcb.kicad_pcb and its schematic 326pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 326pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask 04jj before reusing the design.
