Questions
How big is the Ethernet node PCB?
It measures 81.3 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ethernet node use?
34 parts, built around the ATMEGA88PA-PN and ENC28J60-I/SP. 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 Ethernet node KiCad files?
From the horazont/hint repository on GitHub, at the commit this page was made from: the board is archive/ethernet-node/ethernet-node.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ethernet node design in my own project?
Its repository states no licence, so its author keeps all rights: ask horazont before reusing the design.
