Questions
How big is the Gps radio board PCB?
It measures 25 × 54 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Gps radio board use?
63 parts, built around the ESP32-C6-MINI-1U-H4, MAX-M10N-10B, DM3CS-SF and AP2112K-3.3. 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 radio board KiCad files?
From the tmpk13/telemetry-in-midair repository on GitHub, at the commit this page was made from: the board is gps-radio-board/gps-radio-board.kicad_pcb and its schematic gps-radio-board/gps-radio-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gps radio board 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).
