Questions
How big is the LoconetEsp32 PCB?
It measures 92 × 60 mm and has 4 copper layers, 1.6 mm thick.
What parts does the LoconetEsp32 use?
82 parts, built around the CP2102N-A01-GQFN28R, ESP32-WROOM-32, LM2576S-5.0 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 LoconetEsp32 KiCad files?
From the DccDiyTools/LoconetEsp32 repository on GitHub, at the commit this page was made from: the board is boards/LoconetEsp32/LoconetEsp32.kicad_pcb and its schematic boards/LoconetEsp32/Esp32Supp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LoconetEsp32 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
