Raspberry Pi Pico not included

The WIZnet Ethernet HAT is a Raspberry Pi Pico add-on board that utilizes the W5100S embedded internet controller chip to provide an Ethernet connection to your Raspberry Pi Pico via SPI.

The board supports both 3.3V & 5V and can be mounted directly to your Pico as the HAT pinout matches the Raspberry Pi Pico pin footprint 

About the W5100S Embedded Internet Controller

The W5100S is an embedded Internet controller designed as a full hardwired TCP/IP with WIZnet technology. W5100S provides internet connectivity to your Pico by using SPI (Serial Peripheral Interface). SPI provides an easy connection via external MCU to W5100S. The clock speed of W5100S SPI supports up to 70MHz.

Since the W5100S integrates the hardwired TCP/IP stack with 10/100 Ethernet MAC and PHY, it is truly a one-chip solution for stable internet connectivity. WIZnet’s hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE - and it has been proven through various applications over the last decade.

The W5100S provides four independent sockets to be used simultaneously and 16KB internal memory for data communication. Users can develop an Ethernet application easily by using the simple W5100S socket program instead of handling a complex Ethernet Controller. W5100S also provides WOL (Wake on LAN) and a Power Down Mode in order to reduce power consumption.
