Questions
How big is the LoRaNode PCB?
It measures 60 × 30 mm and has 4 copper layers, 1.6 mm thick.
What parts does the LoRaNode use?
38 parts, built around the E22-900M22S, MAX3483CPA+ and RS485. 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 LoRaNode KiCad files?
From the KunYi/HW_LoRaNode repository on GitHub, at the commit this page was made from: the board is HW/LoRaNode.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LoRaNode design in my own project?
Its repository publishes it under the Apache-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).
