mini型便携Android通讯设备——与外围硬件沟通桥梁 电路方案

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。 mini型便携Android通讯设备实物展示: 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! 附件内容截图: 源文出处:https://www.adafruit.com/products/885
