Questions
How big is the Board1-pdb PCB?
It measures 51 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Board1-pdb use?
32 parts, built around the ACS773LCB-100B-PFF-T, LMR33630ADDA, AMS1117-3.3 and XT60PW-F. 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 Board1-pdb KiCad files?
From the hugo-juarez/fc-pcb repository on GitHub, at the commit this page was made from: the board is board1-pdb/board1-pdb.kicad_pcb and its schematic board1-pdb/board1-pdb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Board1-pdb design in my own project?
Its repository states no licence, so its author keeps all rights: ask hugo-juarez before reusing the design.
