The W5500-EVB-Pico is a microcontroller evaluation board based on the Raspberry Pi RP2040 microcontroller chip and a full hardwired TCP/IP controller W5500 chip.
As the board uses the same pin layout as the Raspberry Pi Pico and includes W5500 embedded ethernet controller, giving you the power of a Raspberry Pi Pico with Ethernet connectivity in a single board!
Updated version! We're now stocking the W5500 version of this board
Don't forget to grab a micro-USB cable for programming. The board comes with a pair of male headers but we also have female and stacking sets in the store.

Hardware Specification
Pinout
The W5500-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 W5500 inside the board. These pins enable SPI communication with W5500 to use the Ethernet function.
If you are using the Ethernet function, these pins cannot be used for any other purpose.
The RP2040 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:
Pin
Name
Description
40
VBUS
Micro-USB input voltage, connected to micro-USB port pin 1. Nominally 5V
39
VSYS
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
37
3V3_EN
Connects to the on-board LDO enable pin. To disable the 3.3V (which also de-powers the RP2040 and W5500), short this pin low
36
3V3
Main 3.3V supply to RP2040 and W5500, generated by the on-board LDO
35
ADC_VREF
ADC power supply (and reference) voltage, and is generated on W5500-EVB-Pici by filtering the 3.3V supply
33
AGND
Ground reference for GPIO26-29
30
RUN
RP2040 enable pin, To reset RP2040, short this pin low/use button

This is a fantastic bit of kit. First time around I didn't pay attention to the pins resevered for the RP2040 module, but a little re-organising and my setup was running and connected to the network in no time. Response is speedy. I'm using the micropython firmware built by WIZnet and have also followed their guidance in building my own just to make sure I am future proof.
Probably the cheapest option for a low power/profile HTTP server out there. Can't beat this little beast. PyCharm and Thoni are great options to run/debug/program it which make life super easy. Integration between these 2 modules seems very robust - never experienced any issues so far
Fantastic. Been waiting for a cheap RJ45 playtoy for IOT things, works well. I used Circuitpython, and for arduino the non arm-mbed OS toolchain (earlphilhower) https://github.com/earlephilhower/arduino-pico
