Arduino Compatible Sensor Shield V2.0 Expansion Board for MEGA2560 (Blue)

1. Using PCB Immersion Gold processing technology, the motherboard will not only all digital and analog interface to the steering gear line order form extended out, but also ad hoc Bluetooth module communication interface, SD card module communication interface, APC220 RF communication interface module and RB URF V2.0 ultrasonic sensor interface.
2. The independent expansion with more user-friendly convenience. Can simplify the circuit, easily be used to connect sensors, a sensor requires only a general 3P sensor wire (regardless of digital cable or analog cable).
