mini型便携通讯设备概述：

        该设计介绍的是搭接Android设备与外围硬件之间通讯的转换工具，也叫"IOIO"。比如外部传感器和伺服系统等硬件之间的通信。与其他的Android通信不一样的是，可以采用该便携设备自带的java库文件，就可以完成Android应用程序代码。不需要额外的Arduino草图!这大大简化了过程,您只需要关注你的Android应用程序代码。

        除了基本的数字输入/输出和模拟输入,该搭接设备还处理PWM,I2C、SPI和UART控制。通过Android手机APP，就可以很容易升级的固件。

Android通讯设备电路功能介绍：

• 46 total I/O pins * - featuring both open-drain, and internal pull up/down, some pins are 5V tolerant
• USB Bluetooth dongle, this particular dongle has been found to be the most compatible with Android devices. See verified devices with this dongle.
• On-board LiPO charger circuit. The LiPO is re-chargeable using any USB power source.
• Included 400 mAh LiPO battery (under the PCB)
• LED indicators for charging and full battery states
• On-board on/off switch
• Female header pins
• 16 analog inputs (10-bit)
• 9 PWM outputs
• 9 pulse inputs
• 4 UART channels
• 3 SPI channels
• 3 TWI (I²C-compatible) channels
• In addition to the headers, 19 of the IOIO pins are also exposed via solder pads for applications where sturdy/permanent connections are needed.
• On-board programmable LED (IOIO "status" LED)
• Maximum 800mA load output
• Solder pad for an optional alcohol sensor

说明：

      很有可能你的Android设备兼容该通讯设备，但我们不能绝对肯定每个Android设备制造商可以修改Android构建。几乎所有的设备将与MicroUSB电缆,但并不是所有将与蓝牙连接,请检查一下!
