Questions
How big is the SBC PCB?
It measures 85 × 54 mm and has 6 copper layers, 1.6 mm thick.
What parts does the SBC use?
329 parts, built around the ARJM11C7-114-BA-EW2, IS21ES08GA-JQLI-TR, ECMF02-2AMX6 and IS43TR16640C-125JBL. 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 SBC KiCad files?
From the ndarash93/SBC repository on GitHub, at the commit this page was made from: the board is SBC.kicad_pcb and its schematic Power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SBC design in my own project?
Its repository states no licence, so its author keeps all rights: ask ndarash93 before reusing the design.
