DFRobot (DFR0673) Voltage Monitoring Module, power Supply 2.5 V to 30 VDC

Ethernet and PoE shield for Arduino - W5500 chipset. The W5500 Ethernetexpansion board is a new member of the DFRobot Ethernet family. It integratesPoE power supply and W5500 Ethernet chip, which can meet the requirements ofgeneral IoT projects. The W5500 chip is a hardwired TCP/IP embedded Ethernetcontroller that provides easier Internet connection to embedded systems. Itenables users to have Internet connectivity in their applications just by usingthe single chip in which TCP/IP stack, 10/100 Ethernet MAC and PHY are embedded.It's faster and easier way rather than using any other Embedded Ethernetsolution. Besides, the W5500's SPI supports 80MHz speed and a new efficient SPIprotocol for high-speed network communication. In order to reduce the powerconsumption of the system, W5500 provides WOL (Wake on LAN) and power-down mode.Specifications:- Silicon Manufacturer: Wiznet- Silicon Core Number: W5500- For Use With: Arduino Ethernet Shield 2- Kit Contents: Ethernet PoE Shield W5500, 2.54 Open-type Jumper Cap x1- Support hardware TCP/IP protocol: TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE- Support 8-channel independent sockets and support WOL Wake-on-LAN- Internal 32KB for TX/RX buffer- On-board level converter circuit- Gravity 3Pin ports for connecting sensors- PoE input: 48V AC/DC (the product is a Class 0 PD device that meets the802.3at standard)- PoE power: up to 12W (the VIN port can output 12V/1A)- SPI clock: 80MHz (max)- PHY: WIZnet W5500- PCB size: 68.6mm x 53.3mm / 2.68 x 2.1inch and overall size: 72.5mm x 53.3mm /2.85 x 2.1inch
