IE shield is an Ethernet Shield instantly enables internet connectivity for Arduino projects with ethernet controller ENC28J60. Just stack it onto an Arduino to create your own networked devices. Easily check connection status with on board indicator lights. Extend your design further with many Electronic / Sensor brick interface and an TF card socket.

This Ethernet shield support the POE function, you can use use the twisted-pair to power it and the Arduino board below, instead using the USB prower or external power jack supply. If your router or moden don't support POE, then you can use the injector cable to mix the signale and power for POE supply.

SPI_CSn Configuration

On the board there is a Cs configuration jumper, you can use it to change the connecting of the chip select pin (CS) on ENC28J60 chip.

As figure 1, CS pin on ENC28J60 is connecting to D10 on Arduino. With this setting, you just can use many Ethernet libraries for Arduino directly, but you cannot use the SD card with the Ethernet function at the same time.

To use the Ethernet module and Micro-SD at the same time, put the jumper as Figure 2 show. With this setting, the SPI_CSn pin of Ethernet module to D8, and the SPI_CSn pin of SD card to D9 pin.
