Introduction:

This is an I2C communication, built -in PWM drive and a clock.This means that this will be very different from the TLC5940 series.You don't need to continuously send a signal to take up your microcontroller!

It is compatible with 5V, which means that you can also control it with a 3.3V single -chip microcomputer and safely drive to the 6V output (when you want to control white or blue indicator lights with 3.4+ positive voltage), it is also possible))

The 6 -address choice foot allows you to hang 62 driver boards on a single I2C bus, with a total of 992 PWM output.That will be a very large resource.

About 1.6kHz adjustable frequency PWM output

To output 12 -bit resolution for step -to -step motors, this means that the update rate at 60Hz can reach 4US resolution

Configurable push -pull output or opening output

Output enable pins can quickly disable all outputs

characteristic:

l pca9685 chip is wrapped in the center of the small board

l Power input terminal

l Green power indicator

l In the 4 groups of 3 needle connectors, it is convenient for you to insert 16 servo motors at one time (the plug of the servo motor is slightly wider than 0.1 ", so you can put 4 to 0.1 connecters)

The reverse polar protection input on the l wiring board

L -Class joint design

L V+Place a large capacitor online (you will need it on some occasions) to enter the maximum voltage peripheral voltage depends on this 10V1000UF capacitor

L all PWM output lines are placed on a 220 ohm series resistor to protect them and can easily drive LEDs.
