I didn't like that these basic little boards available online were overly expensive, and very ugly, so I designed my own!

These are designed to be cost effective whether purchased as-assembled, or if you want to DIY. I also made them look nicer, and added a mounting hole.

Future revisions will shrink the mounting hole, shorten the board, and maybe go for 1mm FR4.

You can purchase these pre-assembled at https://shop.plati.ma/products/10-100mbps-ethernet-board-for-milk-v-duo-and-luckfox-pico if desired.

The assembled versions have a hidden Easter egg, which I did not include in the uploaded gerber of course!

This was a great fun project to learn Kicad with.

Tested and fully functional with 100Mbps download for a few minutes, 0 TX/RX errors.

I have created a Luckfox Pico Mini A/B image with Ubuntu and ethernet enabled which you can download at https://github.com/platima/sbc-images/tree/main/Luckfox/Pico if required
