概 述
X-board是一个独特的Arduino板,它提供的XBee插座,WIZnet以太网端口采用了ATMega328芯片。使用X-board将可以让你的项目通过XBee来控制并能和互联网链接。
使用X-board可以应用于家庭自动化到机器人控制等项目。没有什么是不可能的！
X-board具有8路模拟量I/O引脚和8个数字引脚,其中4个具有PWM（以星号表示），它的XBee插座完美的兼容所有的XBee模块，同时也兼容APC220 RF无线模块和DF-Bluetooth模块。
X-board能通过FTDI编程器或者直接通过ICSP接线端进行编程。X-board通过Mini USB接口提供电源。
你可以在X-board上设置一个Web服务器,通过X-board您可以与远程使用的XBee模块,蓝牙模块或APC模块进行通信。采集的信息可以发送到网站或发微薄。
我们在办公室利用X-board制作了一个项目,通过X-board我们能在网上控制办公室的门。如果我们忘记了我们的RFID门禁卡,那我们只要登录到我们的办公室无线网络并发送一个开门的命令,芝麻开门！门就应声而开!
我们已经创建了一个教程,其中包括零件清单,源代码可以上下载。
