Questions
How big is the LoRa V3-Sensor PCB PCB?
It measures 10 × 10 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LoRa V3-Sensor PCB use?
6 parts, built around the BME680, SHT45-AD1B-R2 and 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-Sensor PCB KiCad files?
From the Strooom/LoRa-V3-Sensor-PCB repository on GitHub, at the commit this page was made from: the board is LoRa-V3-Sensor-PCB.kicad_pcb and its schematic LoRa-V3-Sensor-PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LoRa V3-Sensor PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask Strooom before reusing the design.
