Questions
How big is the Pico LoRa PCB?
It measures 59.7 × 73 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pico LoRa use?
42 parts, built around the DS18B20, MCP73871-1CCI/ML, RFM95W-868S2 and XB8089D. 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 Pico LoRa KiCad files?
From the ElektorLabs/210047-LoRa-with-the-Raspberry-Pi-Pico repository on GitHub, at the commit this page was made from: the board is KiCad Project/Pico_LoRa/Pico_LoRa.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pico LoRa design in my own project?
Its repository states no licence, so its author keeps all rights: ask ElektorLabs before reusing the design.
