Questions

How big is the Interface PCBA PCB?

It measures 99.1 × 73.7 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Interface PCBA use?

104 parts, built around the LM1117-5.0 and XT60-M. 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 Interface PCBA KiCad files?

From the ljparrish/Mobile-Robot repository on GitHub, at the commit this page was made from: the board is Electrical/Interface-PCBA/Interface-PCBA.kicad_pcb and its schematic Electrical/Interface-PCBA/Interface-PCBA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Interface PCBA design in my own project?

Its repository states no licence, so its author keeps all rights: ask ljparrish before reusing the design.
