Questions
What parts does the POE basic use?
8 parts, built around the ESP32-WROOM-32, BME280, SI7053-A20-IM and APDS-9301-020. 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 POE basic KiCad files?
From the DBrianKimmel/Docs repository on GitHub, at the commit this page was made from: the board is Electronics/KiCad/POE-basic/POE-basic.kicad_pcb and its schematic Electronics/KiCad/Basic/Basic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the POE basic design in my own project?
Its repository states no licence, so its author keeps all rights: ask DBrianKimmel before reusing the design.
