16 Channel PWM Servo Driver Board Controller IIC PCA9685

PCA9685 chip is wrapped in the center of the small board Power input terminal Green power indicator It is convenient for you to insert 16 servo motors in 4 groups of 3-pin connectors at one time (the plug of the servo motor is slightly wider than 0.1 “, so you can put 4 pairs of 0.1” connectors) Reverse polarity protection input on the terminal block Cascade design Place a large capacitor on the V + line (you will need it on some occasions). The maximum voltage of the external input depends on this 10V1000uf capacitor A 220 ohm series resistor is placed on all PWM output lines to protect them, and can easily drive the LED.
