Questions
How big is the LoRAndroid PCB?
It measures 39 × 14 mm and has 4 copper layers, 0.8 mm thick.
What parts does the LoRAndroid use?
62 parts, built around the MIC5504-3.3YMT-T5, USBLC6-2P6, DX07P022AA6 and XRCGB32M000FBH50R0. 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 LoRAndroid KiCad files?
From the maximeborges/LoRAndroid-hardware repository on GitHub, at the commit this page was made from: the board is KiCAD/LoRAndroid.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LoRAndroid 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).
