IE shield is a Ethernet shield which use the ENC28J60 Etherent chip instead of the W5100 Ethernet chip. And it integrated the SD slot and may interface breakout.
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 modem doesn't support POE, then you can use a POE injector cable to mix the signale and power for POE supply.
There are many interface breakouts on board. There is a Ethernet SPI control interface on the board, which the same breakout as our ENC28J60 module.
And there are IIC and UART interface on board, some AD interface and GPIO interface. Now you are very easy to make your Ethernet arduino project with variety existing sensor module. And we reserve an PWM/AD interface on board, you can use it as a PWM output and with some components it will be a sample DA ouput.
What's new of v1.1:
There just a small change from v1.0 to v1.1, we change the interface breakout pins to make it compatible with many sensor moulde/ brick 3 PIN interface. So now you can easy use it whith these sensor module or electronic brick.
Note: If you are using this shield with the EtherCard Library make sure you are setting the CS Pin (10) upon initialisation:
ether.begin(sizeof Ethernet::buffer, mymac, 10)
