W5100S-EVB-Pico pin-out is directly connected to the GPIO of RP2040 as shown in the picture
above. It has the same pinout as the Raspberry Pi Pico board. However, GPIO16, GPIO17,
GPIO18, GPIO19, GPIO20, GPIO21 are connected to W5100S inside the board. These pins
enable SPI communication with W5100S to use Ethernet function. If you are using the Ethernet
function, these pins cannot be used for any other purpose.
The RP2040 GPIO used inside W5100S-EVB-Pico is as follows.

Micro-USB input voltage, connected to micro-USB port pin 1. Nominally
5V.
Main system input voltage, which can vary in the allowed range 4.3V to
5.5V, and is used by the on-board LDO to generate the 3.3V.
Connects to the on-board LDO enable pin. To disable the 3.3V (which also
de-powers the RP2040 and W5100S), short this pin low.
Main 3.3V supply to RP2040 and W5100S, generated by the on-board
LDO.
ADC power supply (and reference) voltage, and is generated on W5100S-
EVB-Pici by filtering the 3.3V supply.
Ground reference for GPIO26-29.
RP2040 enable pin, To reset RP2040, short this pin low.
