Questions
How big is the USTSIPIN02 PCB?
It measures 90.9 × 50.3 mm and has 4 copper layers, 1.66 mm thick.
What parts does the USTSIPIN02 use?
174 parts, built around the ATMEGA1284P-AU, BMI-S-204-F, OPA2314M/TR and FT231XQ-R. 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 USTSIPIN02 KiCad files?
From the ust-modules/USTSIPIN02 repository on GitHub, at the commit this page was made from: the board is hw/sch_pcb/USTSIPIN02.kicad_pcb and its schematic hw/sch_pcb/USTSIPIN02.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USTSIPIN02 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
