Questions
How big is the Lora dual PCB?
It measures 87.9 × 65.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lora dual use?
58 parts, built around the ESP-12F, LM2594HVM-5.0, 74LVC2G06GW and LM1117-3.3. 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 dual KiCad files?
From the radioelf/Lora repository on GitHub, at the commit this page was made from: the board is Hard/lora_dual/lora_dual.kicad_pcb and its schematic Hard/Lora_nano/lora-nano.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lora dual design in my own project?
Its repository states no licence, so its author keeps all rights: ask radioelf before reusing the design.
