Description 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.
