The W6100-EVB-PICO is a compact embedded device integrating the Raspberry Pi RP2040 microcontroller and the WIZnet W6100 hardwired internet controller chip. This board provides up to 30x GPIOs, 1x RJ45 port and it supports internet protocols such as TCP, UDP, IPv6, IPv4, etc.

Unlike the W6100-EVB board which is based on a STM32F103VCT6 Cortex-M3, the new W6100-EVB-PICO integrates the RP2040 Raspberry Pi MCU.

• RP2040 — 32-bit Dual Arm Cortex M0+ processor (up to 133MHz)

WIZnet indicates that the W6100 “supports TCP/IP protocols such as TCP, UDP, IPv6, IPv4, ICMPv6, ICMPv4, IGMP, ARP and PPPoE. W6100 also includes 10Base-T / 10Base-Te / 100Base-TX Ethernet PHY and Ethernet MAC Controller which makes it suitable for embedded internet-enabled devices.”

The W6100 also seems to support Wake-on-LAN over UDP, Ethernet PHY power down mode and Clock Switch for power saving. WIZnet suggests using this device for IoT applications, security systems, embedded servers, etc.
