Hardware Specification

Pinout

ترتیب پایه های برد رسپبری پای پیکو با آی سی کنترلر شبکه اترنت W5500 :

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.

I/O	Pin Name	Description
I	GPIO16	Connected to MISO on W5500
O	GPIO17	Connected to CSn on W5500
O	GPIO18	Connected to SCLK on W5500
O	GPIO19	Connected to MOSI on W5500
O	GPIO20	Connected to RSTn on W5500
I	GPIO21	Connected to INTn on W5500
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 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
