With resistance: There is a 220 ohm resistor on all PWM output lines to protect them and easily drive LEDs.
Convenient: It supports using only two pins to control 16 free-running PWM outputs, and you can even link 62 branches to control up to 992 PWM outputs.
High performance: It is convenient for you to insert 16 servo motors into 4 sets of 3-pin connectors at a time. The plugs of the servo motors are slightly wider than 0.1in, so you can put 4 pairs of 0.1in connectors.
High compatibility: 5V compatible, so a 3.3V microcontroller can control it and safely drive it up to 6V output.
Voltage/Resolution: Place a large capacitor on the V+ line, and the maximum external input voltage depends on this 10V1000uf capacitor. 12-bit resolution for each output-for a servo system, this means approximately 4us resolution at a 60Hz update rate.
