Questions
How big is the Ranger24 PCB?
It measures 40.5 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ranger24 use?
39 parts, built around the E28-2G4M27S, ESP32-WROOM-32D, CH340G and AMS1117-3.3. 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 Ranger24 KiCad files?
From the EIectron/ExpressLRS-Ranger-Modul repository on GitHub, at the commit this page was made from: the board is Ranger24.kicad_pcb and its schematic Ranger24.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ranger24 design in my own project?
Its repository states no licence, so its author keeps all rights: ask EIectron before reusing the design.
