Questions
How big is the Link poe PCB?
It measures 72 × 22 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Link poe use?
39 parts, built around the TPSM33620S5QRDNRQ1, BSC010N04LS, NE8FAH and SMBJ33CA. 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 Link poe KiCad files?
From the versioduo/connector repository on GitHub, at the commit this page was made from: the board is link-poe/link-poe.kicad_pcb and its schematic link-poe/PolarityProtection.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Link poe design in my own project?
Its repository states no licence, so its author keeps all rights: ask versioduo before reusing the design.
