Questions
How big is the NavPoTS South PCB?
It measures 58.9 × 58.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the NavPoTS South use?
122 parts, built around the INA226AIDGSR, SIC431AED, LTC4412IS6#TRPBF and GRM21BR61E226ME44L. 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 NavPoTS South KiCad files?
From the RuberDuck9/NavPoTS repository on GitHub, at the commit this page was made from: the board is hardware/kicad/NavPoTS-South/NavPoTS-South.kicad_pcb and its schematic hardware/kicad/NavPoTS-Bridge/NavPoTS-Bridge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NavPoTS South design in my own project?
Its repository publishes it under the AGPL-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).
