Size: 25mm * 61mm * 10.3MM Copy this content and open the Baidu network disk mobile Appwhich is more convenient to operate Introduction: This is an i2c communication with built-in PWM driver and a clock. This means that this will be very different from the TLC5940 series. You don't need to constantly send signals to occupy your microcontroller! It is compatible with 5Vwhich means you can also use 3.3V single chip microcomputer to control and drive to 6V output safely (it is also OK to use 3.4 positive voltage when you want to control white or blue indicator light) 6 addre selection pin allows you to hang 62 driver boards on a single i2c buswith a total of 992 PWM outputs. That would be a huge resource. About 1.6kHz FM PWM output Prepare the output 12-bit resolution for the stepper motorwhich means that the update rate at 60Hz can reach 4us resolution. Configurable push-pull output or open-circuit output The output enable pin can quickly disable all outputs. Features: lPCA9685 chip is wrapped in the center of small Board lPower Input terminal lGreen power indicator lIt is convenient for you to insert 16 servo motors in 4 sets of 3 pin connectors at a time (the plug of servo motor is slightly wider than 0.1 "so you can put 4 pairs of 0.1" connectors) lReverse polarity protection for input on power strip lCascade design lPlace a large capacitance on the V line (you will need it in some occasions) the maximum peripheral input voltage depends on this 10V1000uf capacitor. lAll PWM output cable are equipped with a 220 ohm series resistor to protect them and can easily drive LED.
