Questions
How big is the Loramail PCB?
It measures 43 × 43 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Loramail use?
31 parts, built around the ATMEGA328PB-AU, RFM96W-433S2, BAT54WS and SI2333. 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 Loramail KiCad files?
From the Duckle29/loramail repository on GitHub, at the commit this page was made from: the board is loramail.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Loramail design in my own project?
Its repository states no licence, so its author keeps all rights: ask Duckle29 before reusing the design.
