Questions
How big is the PoE PCB?
It measures 102.5 × 35 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PoE use?
106 parts, built around the TPS563203DRL, TCMT1107, TLV431ACDBZR and TPS23751PWP. 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 KiCad files?
From the ndarash93/PoE repository on GitHub, at the commit this page was made from: the board is PoE.kicad_pcb and its schematic PoE.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PoE design in my own project?
Its repository states no licence, so its author keeps all rights: ask ndarash93 before reusing the design.
