Features:
This is a use i2c communication, with built-in PWM drive and a clock.This means that it will have a big difference compared to TLC5940 series.You don't need to constantly send signals to take up your SCM. It is 5V compatible, which means you can also use a 3.3V single-chip microcomputer control and drive safely to 6V output (when you want to control white or blue light may use 3.4+ positive voltage) Six address selection pin so you can put 62 driver board hung on a single i2c bus, a total of 992 channel PWM output.It will be a very large resources. About 1.6Khz frequency modulation PWM output. Output 12 resolution for stepper motor, which means at 60Hz update rate can reach 4us resolution. Configurable push-pull output or open circuit output. The output enable pin can disable all output quickly. PCA9685 chip was wrapped in the middle of the small plate. Power input terminals. Green power indicator light. In four groups 3-pin connector is convenient for you to insert 16 servo motors once( plug of servo motor is slightly wider than 0.1", so you can put 4 pairs of 0.1" connector) Input reverse polarity protection on the wiring board. Cascade design. V+ wire is placed a large capacitor (in some cases you will need) peripheral input maximum voltage depends on the 10V 1000uf capacitor. Each PWM output wire is placed a 220ohm resistor to protect them, and can easily drive LED.
