V2 ARDUINO MEGA SENSOR expansion shield

The board use of Immersion Gold PCB processing technology, the motherboard will not only all the digital and analog interfaces servo extended line order form out, but also ad hoc Bluetooth module communication interface, SD card module communication interface, APC220 radio frequency module communication interface, and RB URF v1 .1 ultrasonic sensor interface, independent of a more extended use convenient. For beginners, not for the cumbersome and complex circuit connection and a headache, and this sensor expansion board truly simplify the circuit can easily be used to connect the sensor, a sensor requires only a general 3P sensor wire (regardless of digital cable and analog cable), complete the circuit connection, the preparation of the corresponding program to the MEGA Ardui-no controller reads the sensor data, or receive wireless module return data, after arithmetic processing, and ultimately easy to complete your own interactive work.
