Questions
How big is the Lora tracker PCB?
It measures 40 × 95.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lora tracker use?
34 parts, built around the E22-400M30S and RA-01. 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 Lora tracker KiCad files?
From the sh123/esp32_loradv repository on GitHub, at the commit this page was made from: the board is extras/schematics/lora_tracker.kicad_pcb and its schematic extras/schematics/lora_tracker.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lora tracker design in my own project?
Its repository publishes it under the GPL-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).
