Questions
How big is the Maxxfan ethernet controller PCB?
It measures 55.5 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Maxxfan ethernet controller use?
33 parts, built around the MMBT3904. 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 Maxxfan ethernet controller KiCad files?
From the Pekaway/maxx-rj45-controller repository on GitHub, at the commit this page was made from: the board is src/Maxxfan_ethernet_controller.kicad_pcb and its schematic src/Maxxfan_ethernet_controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Maxxfan ethernet controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask Pekaway before reusing the design.
