Pin D0-D53, A0-A16
Support SD Card module
Support URF, ICSP, AREF
It helps in building a simple circuit effortlessly, but for those who are not familiar with the circuit or the slightly more complex circuit it doesn't seem so easy.
The Expansion Shield not only all digital and analog interface to the steering gear out of line order form expansion, but also ad hoc Bluetooth module communication interface, SD card module communication interface, APC220 RF communication interface module, and RB URF ultrasonic sensor interface, the independent expansion a more user-friendly convenience. The Arduino 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 sensors, a sensor requires only a general 3P sensor wire (regardless of number of cable and analog cable), complete the circuit connection, the preparation of the corresponding program to the Arduino MEGA Arduino controller reads the sensor data, or receive wireless module return data, through calculation processing, the final Easy to complete your own interactive works
The IO Expansion shield is designed for those who are familiar with the electronic circuits or universal board with bread board module.
This sensor expansion board is able to easily connect a number of commonly used sensors. For interactive works, the focus should not be on the specific circuit configuration, but on what features needs to be implemented. So for some of the specific function of the sensor module to connect to this sensor expansion board, we need to consider how to use the Arduino.
