Description:
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 Ard controller reads the sensor data, or receive wireless
module return data, after arithmetic processing, and ultimately
easy to complete your own interactive work.
