DFRobot XBoard V2 -A Bridge Between Home And Internet (Arduino Compatible)
This is Version 2.0 of the Xboard. The main improvement is that it now operates at 5V, making it compatible with most sensors and I2C protocol without the need of a voltage level converter.
The XBoard is a unique Arduino board which features a WIZnet ethernet port, an XBee socket, and an ATMega328. This board will add wireless XBee control as well as internet connectivity to your projects. It's great for anything from home automation to robot control. The possibilities are endless!
It has 8 Analogue I/O pins and 8 digital pins, 4 of which have PWM (indicated by an asterisk). It is compatible with all XBee modules, and also comes with an integrated socket for APC220 RF Module or DF-Bluetooth Module. The XBoard can be programmed via an FTDI programmer or via the ICSP header. Power is provided through a Mini USB connector. You can setup a web server through which you may communicate with a remote Arduino using XBee radios, Bluetooth or APC modules. This information can be posted to a website, Twitter or other services.
We have used our XBoard to control our office door from the internet. All we need to do if we forget our RFID badge is to log in to our office WiFi and send the command to open the door! We have created a project guide which includes the list of parts, and source code to get this project going for yourself. The board requires FTDI basic board to upload sketches.
