WIZnet W55RP20-EVB-Pico

The WIZnet W55RP20-EVB-Pico is a Pico ‘clone’ with Ethernet which houses the new W55RP20 from WIZnet – a chip combining the W5500 (a wired TCP/IP controller) and the RP2040. It works mostly** the same as Raspberry Pi Pico board but with additional Ethernet via W5500 and USB-C!

If your Raspberry Pi Pico project needs an Ethernet connection, or you simply want to evaluate this interesting new W55RP20 chip from WIZnet – this is the board for you! Bonus – the W55RP20-EVB-Pico also has a USB-C connection!

A USB-C cable isn’t included, but you can grab one here.

**The board has the same pinout as the Raspberry Pi Pico board. However, GPIO17, GPIO20, GPIO21, GPIO22, GPIO23, GPIO24, and GPIO25 are not available due to the connection inside the board. See the pinout section below for more information.
