SparkFun W5500-EVB-Pico(Sparkfun W5500 Evb Pico)

W5500-EVB-Pico is a microcontroller evaluation board based on the Raspberry Pi RP2040 and fully hardwired TCP/IP controller W5500 � and basically works the same as Raspberry Pi Pico board but with additional Ethernet via W5500.

W5500-EVB-Pico pinout is directly connected to the GPIO of RP2040. It has the same pinout as the Raspberry Pi Pico board. However, GPIO16, GPIO17, GPIO18, GPIO19, GPIO20, GPIO21 are connected to W5500 inside the board. These pins enable SPI communication with W5500 to use Ethernet function. If you are using the Ethernet function, these pins cannot be used for any other purpose.
