Questions
How big is the GPS CLock PCB?
It measures 464 × 33 mm and has 4 copper layers, 1.61 mm thick.
What parts does the GPS CLock use?
210 parts, built around the 74AUP2G17DW, TPS62827DMQ, BQ25892RTW and PMPB17EPX. 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 GPS CLock KiCad files?
From the wcs3/GPS_CLock repository on GitHub, at the commit this page was made from: the board is kicad/GPS_CLock/GPS_CLock.kicad_pcb and its schematic kicad/GPS_CLock/Display.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GPS CLock design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
