Questions
How big is the Gps tracker PCB?
It measures 84.9 × 74.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Gps tracker use?
95 parts, built around the E22-900M22S, LC86LICMD, CH340X and VEML7700-TT. 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 tracker KiCad files?
From the candykingdom/gps-tracker repository on GitHub, at the commit this page was made from: the board is hardware/gps-tracker.kicad_pcb and its schematic hardware/gps-tracker.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gps tracker design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
