Adding an Ethernet Port to your ESP32

Frank Sautter has an interesting post on his blog on adding a physical ethernet connector to an ESP32 development board.  The board he chose was the Waveshare LAN8720 and, apart from Frank Sautter's LAN8720 Adapter Boardone gotcha with GPIO0 during resets, it appears to be a fairly simple build.  The LAN8720 already has (some!) support from Espressif, so this seems like a nice, easy and relatively cheap way to build yourself a WiFi-to-Ethernet gateway.

Frank has detailed the connections for his adapter board and included a nice bottom view (left), so that it should be fairly easy to duplicate his build.  The LAN8720 boards themselves are currently available on eBay for about $3 each.
