Questions
How big is the OSR RN PCB?
It measures 63.5 × 43 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OSR RN use?
77 parts, built around the ATMEGA328-AU, CH340E, AP2112K-3.3 and BC817. 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 OSR RN KiCad files?
From the Open-Things-Network/lora-dev-board repository on GitHub, at the commit this page was made from: the board is v2.0/OSR_RN.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the OSR RN 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).
