Questions
How big is the Lora module PCB?
It measures 27.3 × 24.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Lora module use?
36 parts, built around the PE4259-63. 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 module KiCad files?
From the balcer/lora-modul repository on GitHub, at the commit this page was made from: the board is lora-module.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lora module design in my own project?
Its repository states no licence, so its author keeps all rights: ask balcer before reusing the design.
