Product Details
The W5500 Ethernet expansion board is a great addition to the DFRobot Ethernet family. It combines PoE power supply and the W5500 Ethernet chip, perfect for general IoT projects. The W5500 chip is a reliable TCP/IP embedded Ethernet controller. It makes it super easy to connect embedded systems to the Internet. Just use this single chip with an embedded TCP/IP stack, 10/100 Ethernet MAC, and PHY, and your applications can have Internet access. The proven Hardwired TCP/IP technology supports multiple protocols like TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE. With a 32Kbyte internal memory buffer for Ethernet packet processing, it's a quicker and simpler option than other embedded Ethernet solutions. The W5500's SPI supports 80MHz speed and an efficient protocol for high - speed network communication. It also has WOL (Wake on LAN) and power - down mode to save system power. This expansion board has the same size as Arduino UNO. It uses IEEE 802.3at standard - compliant POE Class 0 power classification and comes with a MicroSD card socket, 2 standard Gravity - 4Pin I2C ports, 1 UART, 4 Gravity - 3Pin digital ports, and 4 analog ports. It's functionally compatible with Arduino Ethernet Shield 2. Key features include support for hardware TCP/IP protocols, 8 - channel independent sockets, WOL Wake - on - LAN, a 32KB TX/RX buffer, an on - board level converter circuit, and Gravity 3Pin ports for sensor connection. Specifications are PoE Input of 48V AC/DC (Class 0 PD device meeting 802.3at standard), PoE Power up to 12W (VIN port can output 12V/1A), SPI Clock up to 80MHz, PHY as WIZnet W5500, PCB Size of 68.6mmx53.3mm / 2.68 x 2.1 inch, and Overall Size of 72.5mmx53.3mm / 2.85 x 2.1 inch. It also has a product wiki and the shipping list includes an Ethernet & PoE Shield for Arduino - W5500 and a 2.54 Open - type Jumper Cap.
Using this W5500 Ethernet and PoE Shield for Arduino is quite straightforward. First, make sure your Arduino board is powered off. Then, connect the shield to your Arduino UNO as they are the same size, so it should fit easily. If you want to use PoE, connect the power source with 48V AC/DC as it's a Class 0 PD device. You can connect sensors to the Gravity 3Pin ports. For network communication, the shield makes it easy for your Arduino projects to access the Internet. Just use the single W5500 chip and follow the normal network setup steps. When it comes to storage, you can use the MicroSD card socket. Remember to keep the power supply within the specified range. The PoE power is up to 12W and the VIN port can output 12V/1A. Don't exceed the SPI clock speed of 80MHz. For maintenance, keep the shield in a dry and clean place. If it gets dirty, you can use a soft, dry cloth to gently wipe it. Avoid exposing it to extreme temperatures or humidity as it may affect the performance of the components.
