WIZnet W5500-EVB-Pico2

The WIZnet W5500-EVB-Pico2 is a microcontroller board based on the Raspberry Pi RP2350 and fully hardwired TCP/IP controller W5500 – it essentially works the same as Raspberry Pi Pico 2 but with additional Ethernet via W5500 and USB-C!

The board can also support PoE via the optional WIZPoE-P1 PoE add-on module.

The W5500-EVB-Pico2 pinout is directly connected to the GPIO of RP2350 as shown in the pinout image. It has the same pinout as the Raspberry Pi Pico2 board. However, GPIO16, GPIO17, GPIO18, GPIO19, GPIO20, GPIO21 are connected to W5500 inside the board. These pins enable SPI communication with W5500 to use the Ethernet function. If you use the Ethernet function, these pins cannot be used for any other purpose.

The RP2350 GPIO used inside W5500-EVB-Pico is as follows.

Apart from GPIO and ground pins, there are 7 other pins on the main 40-pin interface:
