Questions
How big is the ExpressLRS Nano Receiver PCB?
It measures 12.9 × 13.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ExpressLRS Nano Receiver use?
34 parts, built around the ESP8285, SX1280IMLTRT, 2450FM07D0034T and AP2210N-3.3TRG1. 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 ExpressLRS Nano Receiver KiCad files?
From the EIectron/ExpressLRS-Nano-Receiver repository on GitHub, at the commit this page was made from: the board is ExpressLRS-Nano-Receiver.kicad_pcb and its schematic ExpressLRS-Nano-Receiver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ExpressLRS Nano Receiver design in my own project?
Its repository states no licence, so its author keeps all rights: ask EIectron before reusing the design.
