Questions
How big is the MULTIGW PCB?
It measures 40 × 68 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MULTIGW use?
32 parts, built around the ESP32-WROOM-32, AMS1117-3.3, LAN8720A-CP and HR911105A. 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 MULTIGW KiCad files?
From the nuclearcat/ESP32ETH repository on GitHub, at the commit this page was made from: the board is MULTIGW.kicad_pcb and its schematic MULTIGW.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MULTIGW design in my own project?
Its repository publishes it under the LGPL-2.1 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
