W5500 Ethernet with POE Mainboard SKU: DFR0342

by DFRobot



Overview

The W5500 Ethernet mainboard is the newest member of the DFRobot Ethernet family. It Is a microcontroller based on the ATmega32u4 and W5500 Ethernet chip with the same footprint as an Arduino Leonardo board, as well as being compatible with most Arduino shields and sensors, making it suitable for many kinds of IOT applications. The W5500 chip is a hardwired TCP/IP embedded Ethernet chip that provides easy internet connection for embedded systems. The board has the TCP/IP stack, 10/1000 ethernet MAC and PHY embedded, allowing internet connectivity in the users application using just the board and nothing else. The W5500 Ethernet mainboard uses a high-efficiency SPI protocol which supports a speed of 80MHZ for high speed network communication. In order to reduce power consumption it also includes WOL (wake on LAN) and power down modes. The board can be powered using a regular VIN, or POE as the power supply. It also integrates a power regulation chip that allows it to work under a complex environment.
