Questions
How big is the Millimobile circuit PCB?
It measures 15 × 20 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Millimobile circuit use?
38 parts, built around the ISP2053-AX-RS, CSD17585F5T, SN74LVC1G3157YZP and SMS7630-079LF. 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 Millimobile circuit KiCad files?
From the zenglhardt/millimobile-platform repository on GitHub, at the commit this page was made from: the board is Millimobile-circuit.kicad_pcb and its schematic Millimobile-circuit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Millimobile circuit design in my own project?
Its repository states no licence, so its author keeps all rights: ask zenglhardt before reusing the design.
