WIZnet
The WIZnet W6100-EVB-Pico2 is a microcontroller board based on the Raspberry Pi RP2350 and fully hardwired TCP/IP controller W6100, with Ethernet via the W6100 and USB-C!
The board can also support PoE via the optional WIZPoE-P1 PoE add-on module.
The W6100-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 Pico 2 board. However, GPIO16, GPIO17, GPIO18, GPIO19, GPIO20, GPIO21 are connected to W6100 inside the board. These pins enable SPI communication with W6100 to use the Ethernet function. If you use the Ethernet function, these pins cannot be used for any other purpose.
MicroPython is not yet supported as the wiznet5k library does not yet support the W6100 chip. WIZnet are working on this. CircuitPython may support the chip in IPV4 mode only.
The RP2350 GPIO used inside W6100-EVB-Pico is as follows.
| I/O | Pin Name | Description |
| I | GPIO16 | Connected to MISO on W6100 |
| O | GPIO17 | Connected to CSn on W6100 |
| O | GPIO18 | Connected to SCLK on W6100 |
| O | GPIO19 | Connected to MOSI on W6100 |
| O | GPIO20 | Connected to RSTn on W6100 |
| I | GPIO21 | Connected to INTn on W6100 |
| 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 W6100), short this pin low. |
| PIN36 | 3V3 | Main 3.3V supply to RP2350 and W6100, generated by the on-board LDO. |
| PIN35 | ADC_VREF | ADC power supply (and reference) voltage, and is generated on W6100-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. |
