Product description: W55RP20-EVB-PICO - board with RP2040 microcontroller and Ethernet - WIZnet
W55RP20-EVB-Pico is a development board based on the dual-core RP2040 microcontroller (ARM Cortex M0+ up to 133 MHz) and integrated W5500 Ethernet controller . With a built-in RJ45 port, support for TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE protocols and 8 independent hardware TCP/IP sockets, the board provides a stable 10/100 Mbps network connection . It offers 22 GPIOs , including 4 ADC inputs, UART, I2C, SPI, PWM and USB Type-C interfaces for power supply and programming. Equipped with 2 MB Flash memory , it allows you to run code directly from external Quad-SPI memory. Built-in Power over Ethernet (PoE) and SWD debugging make it an ideal solution for IoT, automation and intelligent networking projects.

WIZnet board equipped with a Raspberry Pi RP2040 microcontroller and an Ethernet TCP/IP W5500 system.
