Questions
How big is the Poe4pi PCB?
It measures 65 × 56 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Poe4pi use?
31 parts, built around the TPS23751PWP, DF01S and SMAJ58A. 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 Poe4pi KiCad files?
From the Slenderman00/poe4pi-5 repository on GitHub, at the commit this page was made from: the board is poe4pi.kicad_pcb and its schematic poe4pi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Poe4pi design in my own project?
Its repository states no licence, so its author keeps all rights: ask Slenderman00 before reusing the design.
