Questions
How big is the LAN Module PoE Castellated PCB?
It measures 25.3 × 61 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LAN Module PoE Castellated use?
104 parts, built around the ESP32-U4WDH, LV2842XLVDDCR-JSM, SI3404-TP and B5819W. 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 LAN Module PoE Castellated KiCad files?
From the jorticus/esp32-poe-dev repository on GitHub, at the commit this page was made from: the board is LAN-Module-PoE-Castellated.kicad_pcb and its schematic LAN-Module-1P.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LAN Module PoE Castellated design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
