W5500 PoE Ethernet Expansion Board

SKU: DFR0850

The W5500 PoE Ethernet Expansion Board, part of the DFRobot Ethernet family, integrates a PoE power supply with a W5500 Ethernet chip, designed to meet the needs of IoT projects by providing a hardwired TCP/IP embedded Ethernet controller for easier Internet connectivity. The W5500 chip offers a singular solution for embedding Internet connectivity, hosting TCP, UDP, IPv4, and more protocols, with a 32Kbyte internal memory buffer for efficient Ethernet packet processing. Supporting high-speed SPI communication up to 80MHz, the board features WOL and power down modes to minimize power consumption. With dimensions matching the Arduino UNO, it complies with IEEE 802.3at POE Class 0 standards and includes a MicroSD card socket, multiple I2C ports, UART, digital and analog ports, making it a versatile choice for developers.

    Pinout

    The board has extra pin 11 and 12 for easy connection to the w5500 reset pin. The board comes with a jumper cap. If you do not use the w5500 reset function, please remove the jumper cap to avoid affecting the normal use of the pins.

    NOTE

    • This board has a POE power supply unit whose voltage can reach up to 50V. Although it is not harmful for humman beings, please do not touch the circuit borad with your hands or other conductors since there are some low-voltage circuits on the board that cannot bear such high voltage. Otherwise, product damage may occur.
    • The transformer and power chip used in the board will generate a lot of heat during high-load use. Therefore, please maintain a good heat dissipation environment during using to avoid damage to the product due to overheating and be careful of high temperature burns.
