With the same size as Arduino UNO, this W5500 Ethernet expansion board adopts IEEE 802.3at standard-compliant POE Class 0 power classification and offers MicroSD card socket and 2 standard Gravity-4Pin I2C ports, 1 UART, 4 Gravity-3Pin digital ports and 4 analog ports, etc. To vik09: I guess it's doable but you need the arduino to be a usb host controller, unless you have a due, tre, intel galileo or any other arduino board with built in usb host/otg, you need a usb host shield. In order to reduce the power consumption of the system, W5500 provides WOL (Wake on LAN) and power-down mode. Besides, the W5500’s SPI supports 80MHz speed and a new efficient SPI protocol for high-speed network communication. It’s faster and easier way rather than using any other Embedded Ethernet solution.
W5500 embeds the 32Kbyte internal memory buffer for the Ethernet packet processing. The Hardwired TCP/IP is the market-proven technology that supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE protocols. It enables users to have Internet connectivity in their applications just by using the single chip in which TCP/IP stack, 10/100 Ethernet MAC, and PHY are embedded. The W5500 chip is a Hardwired TCP/IP embedded Ethernet controller that provides easier Internet connection to embedded systems. Then in the search box, begin searching for 'SparkFun LTE Shield.' Once your search is narrowed down, select the SparkFun LTE Shield library and click 'Install. In the Arduino IDE, navigate to Sketch > Include Library > Manage Libraries. LiPo Battery A 3.7-4.2V LiPo battery can be connected to the black 2-pin JST connector. The SparkFun LTE Shield Library is available in the Arduino library manager. You can utilize Sparkfun’s USB shield instead.
Arduino The shield receives power from the Arduino’s 5V supply pin. I used the USB host shield from Arduino but it’s now discontinued. It integrates PoE power supply and W5500 Ethernet chip, which can meet the requirements of general IoT projects. The shield is designed to take power from one of three sources: 1. The W5500 Ethernet expansion board is a new member of the DFRobot Ethernet family.
