Hello all, I have this module for servo using I2C. It works. OK. But my servos are 8.5V high voltage high torque motors. Motors haves on PWM input side 4-8V. Can I use this module for PWM? and Servo motors power supply have 8.5V? GND will be connected from Arduino to module and servo power supply. …

Adafruit 12b PWM controler PCA9685 - use with 8.5V high voltage servo

A PCA9685 servo board already has 220ohm resistors in series with it's outputs.

Don't confuse servo power with servo data signals.
