The W5100S-EVB-Pico is a microcontroller evaluation board based on the Raspberry Pi RP2040 microcontroller chip and full hardwired TCP/IP controller W5100S chip. The W5100S-EVB-Pico has the same role as the Raspberry Pi Pico platform and includes W5100S, so the Ethernet function is basically included.

Hardware Specification


W5100S-EVB-Pico pinout 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 the Ethernet function. If you are using the Ethernet function, these pins cannot be used for any other purpose.
