DescriptionDFRduino Ethernet Shield is an easy way to connect your Arduino board to the Internet. Just attach the shield to your board, upload Ethernet sample codes, and you’re good to go. The WizNet Ethernet chip integrates full hardwired TCP/IP protocol stacks and has four independent hardware SOCKETs. Your board can communicate with WizNet and an SD card through the SPI interface. DFRduino Ethernet Shield supports both Arduino UNO and Mega series. Its current hardware version, V3.0, has an upgraded chip that has lower power consumption, lower heat, and higher performance.Connection DiagramFEATURESFull hardwired TCP/IP protocol stacksSupport 4 independent hardware SOCKETs simultaneouslyInternal 16K bytes memory TX/ RX Buffers for TCP/IP packet processingSupport auto-negotiationAPPLICATIONSIoT projectSPECIFICATIONOperating Voltage: 5V16KB TX/RX Buffers4 Independent hardware socketsFull-hardware TCP/IP protocol stacks MAC PHYOperating Temperature: -40℃ ~ 85℃Dimension: 70x55x30mm (2. 76×2. 15×1. 18″)DOCUMENTSProduct wikiSchematicsDimensionDXFSTPW5100S DatasheetSHIPPING LIST1 x DFRduino Ethernet W5100S Expansion Board
