Questions
How big is the LoRa V3-Mini PCB PCB?
It measures 52 × 18 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LoRa V3-Mini PCB use?
25 parts, built around the TSL25911FN. 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 V3-Mini PCB KiCad files?
From the Strooom/LoRa-V3-Mini-PCB repository on GitHub, at the commit this page was made from: the board is LoRa-V3-Mini-PCB.kicad_pcb and its schematic LoRa-V3-Mini-PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LoRa V3-Mini PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Strooom before reusing the design.
