Questions
How big is the LORA BOARD PCB?
It measures 32 × 96.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LORA BOARD use?
53 parts, built around the BC817, DMG2301L and RFM95W. 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 BOARD KiCad files?
From the Open-Things-Network/lora-dev-board repository on GitHub, at the commit this page was made from: the board is v1.1/LORA_BOARD.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LORA BOARD 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).
