It is great to see someone else make use of that adapter. It expands the Arduino MKR form factor to pmod and click. Soldering optional.

Funny test: the @fpgahelper (thanks for the boards) Ziggy Bridge MKR board with a LAN8720 PMOD and AXE5000 (@AlteraFPGA_ Agilex5). Everything with @enjoy_digital LiteX/LiteEth. netboot works out of the box to load LiteX-bare-demo and donut! 🎇🥂

All three are equivalent. The first two being the same is absolutely intuitive, but it took me a while to realize how and why the last one works too. I'll probably remember this for the rest of my life as a "one weird trick" that can come in handy sometimes.
