README
readme.mdPhy Test
This project is an experiment in directly incorproating an ethernet interface onto a PCB. As of now it's still a work in progress and should not be used.
Setup
After building the PCB, use an Arduino ISP to burn an Arduino Leonardo bootloader.
When programming the board, treat it like an Arduino Leonardo.

Questions
How big is the PhyTest PCB?
It measures 85 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PhyTest use?
53 parts, built around the ATMEGA32U4-AU and W5500. 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 PhyTest KiCad files?
From the pklopping/PhyTest repository on GitHub, at the commit this page was made from: the board is PhyTest/PhyTest.kicad_pcb and its schematic PhyTest/PhyTest.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PhyTest design in my own project?
Its repository states no licence, so its author keeps all rights: ask pklopping before reusing the design.
