Feature:1. It is convenient for you to insert 16 servo motors in 4 groups of 3pin connectors at a time.2. The plug of the servo motor is slightly wider than 0.1in, so you can put 4 pairs of 0.1in connectors.3. Place a large capacitor on the V+ line, and the maximum external input voltage depends on this 10V1000uf capacitor.4. There is a 220 ohm resistor on all PWM output lines to protect them and drive the LED easily.5. 5V compliant, so a 3.3V microcontroller can control it and safely drive it up to 6V outputs.6. Support using only two pins to control 16 freerunning PWM outputs you can even chain up 62 breakouts to control up to 992 PWM outputs.7. 12bit resolution for each output for servos, that means about 4us resolution at 60Hz update rate.Specification:Item Type: PWM Servo DriverProduct Material: Printed Circuit BoardModel: PCA9685.Package List:1 x PWM Servo Driver
