Analog Wiring Example

RoboClaw uses a high speed 12 bit analog converter. Its range is 0 to 2V. The analog pins

are protected and 5V tolerant. The potentiometer range will be limited if 5V is utilized as the

reference voltage. A simple resistor divider circuit can be used to reduce the on board 5V to 2V

for use with a potentiometer(POT). See the below schematic. The POT acts as one half of the

resistor divider. If using a 5k potentiometer R1 / R2 = 7.5k, If using a 10k potentiometer R1 / R2

= 15k and if using a 20k potentiometer R1 / R2 = 30k.

Set mode 3 with option 1 if using autocalibration. Center the potentiometers before applying

power. The S1 potentiometer will control the motor 1 direction and speed. The S2 potentiometer

will control the motor 2 direction and speed.

For model specic pinout information please refer to the data sheet for the model being used.
