Evaluation Boards

W55RP20-EVB-Picolink

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

W5500link

The W5500 chip is a Hardwired Internet controller with an integrated full TCP/IP stack, enabling Internet connectivity via SPI with up to 80MHz speed. It combines 10/100 Ethernet MAC and PHY for stable connectivity and supports protocols like TCP, UDP, IPv4, among others. With 8 sockets and 32KB internal memory, it simplifies Ethernet application development and includes features like WOL and Power Down Mode for energy efficiency.
