Questions
How big is the STM32POE PCB?
It measures 70 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the STM32POE use?
114 parts, built around the TPS2378DDA, LM5164DDA, LAN8720A-CP and 100N10NF. 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 STM32POE KiCad files?
From the KunoDLK/POE-Test repository on GitHub, at the commit this page was made from: the board is Master_POE_STM32F4/STM32POE.kicad_pcb and its schematic Master_POE_STM32F4/Modules/BQ25758A.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32POE design in my own project?
Its repository states no licence, so its author keeps all rights: ask KunoDLK before reusing the design.
