==Overview==

[[File:Iboardex3.jpg|thumb|400px|right]]
[[IBoard|Iboard]] Ex is a unique Arduino board which features a WIZnet Ethernet port with POE, an XBee socket, nRF24L01+ module interface, Micro SD socket and an ATMEGA32U4. This board will add wireless XBee control as well as internet connectivity to your projects. And don’t need any external programmer, just connect it with PC by a USB cable. It’s great for anything from home automation to robot control. The possibilities are endless!

Ethernet RJ45 with POE, Micro-SD Socket, XBee interface, nRF24L01+ interface, analog/digital electronic brick interfaces and so on, many interfaces are designed 
and broke out for many projects as Ethernet communication, wireless communication, mass storage, digital control and signal sample.

===Xbee Communication Interface===

==Software==
[[IBoard]] Ex is used the ATmega32U4, and compatible with Arduino Leonardo. 

Now the SD and Ethernet library is not support well with Arduino Leonardo, so when you use the [[IBoard]] Ex with these libraries, you need to modify something to make the code work. 

With embedded bootloader, [[IBoard]] Ex is easy to use by Arduino IDE through USD, and chooses the selection of the "Board" menu with "Arduino Leonardo". ISP of 
Atmega32U4 is broke out for download firmware easily.
