Questions
How big is the GPSDO LCD-2 PCB?
It measures 130.8 × 53.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GPSDO LCD-2 use?
95 parts, built around the NEO-6M, OPA692ID and LMP7731MF. 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 GPSDO LCD-2 KiCad files?
From the EA5IOT/EA5IOT_GPSDO repository on GitHub, at the commit this page was made from: the board is Test PCB/GPSDO-LCD-2/GPSDO-LCD-2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the GPSDO LCD-2 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).
