Item Type: PWM Servo Driver_x000D_ Product Material: Printed Circuit Board_x000D_ Model: PCA9685 1It is convenient for you to insert 16 servo motors in 4 groups of 3?pin connectors at a time. 2The plug of the servo motor is slightly wider than 0.1in, so you can put 4 pairs of 0.1in connectors. 3Place a large capacitor on the V+ line, and the maximum external input voltage depends on this 10V1000uf capacitor. 4There is a 220 ohm resistor on all PWM output lines to protect them and drive the LED easily. 55V compliant, so a 3.3V microcontroller can control it and safely drive it up to 6V outputs. 6Support using only two pins to control 16 free?running PWM outputs you can even chain up 62 breakouts to control up to 992 PWM outputs. 712?bit resolution for each output ? for servos, that means about 4us resolution at 60Hz update rate.1 x PWM Servo Driver
