Nice Sensor shield of MEGA Rev3, Easy prototyping and Very convenient especially for 3PIN (G V S) connections. There are tons of ground and VCC headers making really it easy to connect various Arduino modules and sensors with DuPont style cables.
This sensor shield board really simplify the circuit and easily connect commonly used sensors.The board is having digital and analog interface, Bluetooth module communication interface, SD Card module communication interface, APC 220 radio frequency module interface, etc.
