I want to drive in Raspberry Pi this servo with max power to get max torque available, 8.4 V with 4.5 A, but I haven't found any PWM servo driver I2C interface which can stand the 8.4 V.
The pca9685 spec shows max 6 VDC for the servo.
The servo spec says the voltage range up to 8.4 V max, with 8.4 V I get more torque which is what I need.
What can I do to run that servo at full power? Is there any other PWM servo driver I2C interface board that I can use?
