You want to do a cool robot, maybe want to do a six-legged walking robot, or just a piece of art with many moving parts. You may also want to use precise PWM output drive many LED indicator. Then you realize that your microcontroller PWM limited number of output!What will happen next? You can give up or you can use this handyPWM servo drive small plate.

 

Introduction: 

This is a communication using i2c, built-in PWM driver and a clock.This means that this will be very different from the TLC5940 series.You do not need to constantly send signals to take up your microcontroller!

It is 5V compatible, which means you can also use 3.3V MCU control and safe drive to 6V output (when you want to control the white or blue LED with a positive voltage of 3.4 + is also possible)

6 address selection pin allows you to 62 drive board hanging in a single i2c bus, a total of 992 PWM output. That would be a very large resource.

About 1.6Khz adjustable frequency PWM output

12-bit resolution for stepper motor output, which means that the update rate of 60Hz can reach 4us resolution

Configurable push-pull output or open-circuit output

The output enable pin enables fast disabling of all outputs

characteristic: 

l  Central PCA9685 chip was wrapped in a small plate

l  power input terminals

l  green power indicator

l  allowing you to group 3 at 4 pin connector 16 is inserted in a servo motor (servo motor plug slightly wider than the 0.1 ", so you can put four pairs of 0.1" connector)

l  reverse polarity protection terminal board input

l  cascade design

L  V + line to place a large capacitor (in some cases you'll need) the maximum voltage depends on the peripheral input capacitance 10V1000uf

l  All PWM output lines have put a 220 ohm series resistor to protect them, and can easily drive the LED.
