The WIZnet W5100S-EVB-Pico2 is a microcontroller board based on the Raspberry Pi RP2350 and fully hardwired TCP/IP controller W5100S – it essentially works the same as Raspberry Pi Pico 2 but with additional Ethernet via W5100S and USB-C!
The board can also support PoE via the optional WIZPoE-P1 PoE add-on module.
The W5100S-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 W5100S inside the board. These pins enable SPI communication with W5100S 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 W5100S-EVB-Pico is as follows.
I/O | Pin Name | Description |
I | GPIO16 | Connected to MISO on W5100S |
O | GPIO17 | Connected to CSn on W5100S |
O | GPIO18 | Connected to SCLK on W5100S |
O | GPIO19 | Connected to MOSI on W5100S |
O | GPIO20 | Connected to RSTn on W5100S |
I | GPIO21 | Connected to INTn on W5100S |
I | GPIO24 | VBUS sense - high if VBUS is present, else low |
O | GPIO25 | Connected to user LED |
I | GPIO29 | Used in ADC mode (ADC3) to measure VSYS/3 |
Apart from GPIO and ground pins, there are 7 other pins on the main 40-pin interface:
Pin No. | Pin Name | Description |
PIN40 | VBUS | USB-C input voltage, connected to USB-C port pin 1. Nominally 5V. |
PIN39 | 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 . |
PIN37 | 3V3_EN | Connects to the on-board LDO enable pin. To disable the 3.3V (which also de-powers the RP2350 and W5100S), short this pin low. |
PIN36 | 3V3 | Main 3.3V supply to RP2350 and W5100S, generated by the on-board LDO. |
PIN35 | ADC_VREF | ADC power supply (and reference) voltage, and is generated on W5100S-EVB-Pico by filtering the 3.3V supply. |
PIN33 | AGND | Ground reference for GPIO26-29. |
PIN30 | RUN | RP2350 enable pin, To reset RP2350, short this pin low. |
You may be wondering what the difference is between the different models of WIZnet boards we offer. This mostly comes down to the TCP/IP controller chip used.
