Arduino UNO SPE Shield adds Single Pair Ethernet (SPE) and RS485 to Arduino UNO and compatible boards, notably the Arduino UNO R4, via a Microchip LAN8651 SPE controller. Single Pair Ethernet relies ...

"Just two years ago, over 80 percent of AI clusters ran on InfiniBand, but Ethernet is striking back rapidly—gaining significant ground as reflected by the astonishing surge in Ethernet Data ...

The USB port, for sure – and if you’re daring enough to wire Ethernet to a Pico ... Check the datasheet for an example schematic and compare with yours. Another pitfall to mind.

If you're unsure how to do this, you can google for the pinout of your Arduino and the ethernet controller. There are different versions of the ENC28J60 out there. I'm using a shield for the Arduino ...

The library cannot currently be used with hardware based on the ENC28J60 chip – such as the Nanode or the Nuelectronics Ethernet Shield. For those, there is an alternative library available.
