Questions
How big is the LoRa TM PCB?
It measures 28 × 58 mm and has 2 copper layers, 1.59 mm thick.
What parts does the LoRa TM use?
18 parts, built around the E32-433T33S, FT232RL and B5819W. 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 TM KiCad files?
From the NARAE-INHA-UNIV/LoRa_TM repository on GitHub, at the commit this page was made from: the board is LoRa_TM/LoRa_TM.kicad_pcb and its schematic LoRa_TM/LoRa_TM.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LoRa TM design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
