Servo Click Board
Servo click is a 16-channel PWM servo driver with the voltage sensing circuitry. It can be used to simultaneously control 16 servo motors, each with its own programmable PWM signal. The frequency of the control PWM signal can be programmed in the range from 24 Hz to 1526 Hz, which is an ideal range for driving various types of servos. An accurate 16bit A/D converter is used to sample the voltage drop across the shunt resistor on each of the 16 channels, giving feedback on the servo current consumption. This way, Servo click is able to provide an information about the servo operation parameters, with no additional modifications of the servo itself.
