Questions
How big is the SerialGPS PCB?
It measures 73.7 × 48.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SerialGPS use?
56 parts, built around the MAX3232ID, LM1117-3.3 and NEO-M8N. 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 SerialGPS KiCad files?
From the Ehryk/ehryk.github.com repository on GitHub, at the commit this page was made from: the board is Circuits/SerialGPS/SerialGPS.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SerialGPS design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ehryk before reusing the design.
