(170) 16 Channel PWM/Servo/Servo Driver Board Controller IIC PCA9685

(170) 16 Channel PWM/Servo/Servo Driver Board Controller IIC PCA9685 Description

(170) 16 Channel PWM/Servo/Servo Driver Board Controller IIC PCA9685 Description: This is a built-in PWM driver and clock that uses I2C communication. This means it will be very different from the TLC5940 series. You don't need to constantly send signals to occupy your microcontroller! It's 5V compatible, meaning you can also control it with a 3.3V microcontroller and safely drive it to the 6V output (3.4V + positive voltage is also OK if you want to control the white or blue LEDs). With the 6 address selection pins, you can connect 62 driver boards to a single I2C bus, for a total of 992 PWM outputs. That would be a very large resource.
Over 1.6 kHz PWM output with adjustable frequency
Ready to output a 12-bit resolution for stepper motors, which means a resolution of 4 µs at a 60 Hz update rate
Configurable push-pull or open-circuit output
Output enable pin quickly disables all outputs
The PCA9685 chip is wrapped in the center of the small board
Power input connector
Green power indicator
It is convenient for you to plug 16 servo motors simultaneously into 4 sets of 3-pin connectors (the servo motor connector is slightly wider than 0.1 inch, so you need 4 pairs of 0.1-inch connectors) (can be plugged in).
Input reverse polarity protection on the terminal block
Cascade circuit
Place a large capacitor on the V+ line (you will need this in some cases). The peripheral input voltage depends on this. 10V 1000µF capacitor
Place a 220-ohm series resistor on all PWM output lines to protect them and easily control the LED.
