WIZnet W6100-EVB-Pico [Discontinued]

The W6100-EVB-Pico from WizNET is a microcontroller evaluation board based on the Raspberry Pi RP2040 microcontroller chip and a full hardwired TCP/IP controller W6100 chip which supports IPv6!

The board uses the same pin layout as the Raspberry Pi Pico and includes a W6100 embedded ethernet controller, giving you the power of a Raspberry Pi Pico with IPv6-supported Ethernet connectivity in a single board!

There’s a detailed getting started guide to help you get up and running quickly.

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.

Comes with a pair of loose male header pins to solder to the board (if you want to).

Hardware Specification

Pinout

The W6100-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 W6100 inside the board. These pins enable SPI communication with W6100 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 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	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 W6100), short this pin low
36	3V3	Main 3.3V supply to RP2040 and W6100, generated by the on-board LDO
35	ADC_VREF	ADC power supply (and reference) voltage, and is generated on W6100-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
