W55RP20-EVB-PICO

Overview

W5500-EVB-Pico is a microcontroller evaluation board based on the Raspberry Pi RP2040 and fully hardwired TCP/IP controller W5500 – and basically works the same as Raspberry Pi Pico board but with additional Ethernet via W5500.

  • Raspberry Pi Pico Clone
  • Ethernet (W55RP20 Hardwired TCP/IP CHIP)

Hardware Specification

Pin-out

W5500-EVB-RP2040

W55RP20-EVB-Pico pinout is directly connected to the GPIO of RP2040 as shown in the above picture. It has the same pinout as the Raspberry Pi Pico board. However, GPIO17, GPIO20, GPIO21, GPIO22, GPIO23, GPIO24, and GPIO25 are not available due to the connection inside the board.

The W55RP20 GPIO used inside W55RP20-EVB-Pico is as follows.

I/OPin NameDescription
OGPIO16DCDC Mode Select Pin
IGPIO18VBUS sense - high if VBUS is present, else low
OGPIO19Connected to user LED
IGPIO29Used 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 NameDescription
PIN40VBUSMicro-USB input voltage, connected to micro-USB port pin 1. Nominally 5V.
PIN39VSYSMain 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 .
PIN373V3_ENConnects to the on-board LDO enable pin. To disable the 3.3V (which also de-powers the RP2040 and W5500), short this pin low.
PIN363V3Main 3.3V supply to RP2040 and W5500, generated by the on-board LDO.
PIN35ADC_VREFADC power supply (and reference) voltage, and is generated on W5500-EVB-Pico by filtering the 3.3V supply.
PIN33AGNDGround reference for GPIO26-29.
PIN30RUNRP2040 enable pin, To reset RP2040, short this pin low.
