1pc PCA9685 16 Channel 12 Bit PWM Servo Driver Board PCA9685 For Arduino IIC Module Raspberry a L1X4

Label: Yes

This is communication with i2c, built-in PWM drivers, and clocks. This means that this will be very different from the TLC5940 series. You don't need to keep sending signals to keep your microcontroller!

It's 5V compatible, which means you can also use a 3.3V microcontroller to control it and safely stick to the 6V output (if you want to control the white or blue LEDs with 3.4+ positive voltage you can too)

The 6 address selection pins allow you to put 62 driver boards on an i2c bus for a total of 992 PWM outputs. This would be a great resource.

The approx. 1.6Khz FM PWM output means that a 60Hz refresh rate can reach 4us resolution for a stepper motor ready to output 12-bit resolution. Configurable push-pull outputs or open-circuit outputs, and the output enable pin quickly disables all outputs.

Characteristic:

l PCA9685 chip wrapped in the middle of the board

l Power input terminal

l Green power indicator

l Insert a 4-pin 3-pin connector, 16 servo motors can be easily inserted at a time (the servo motor connector is slightly wider than 0.1", so you can put 4 pairs of 0.1" connectors)

l The polarity of the reverse polarity is input on the terminal block

L Cascade design

The line places a large capacitor (in some cases you will need) and the peripheral input maximum voltage depends on this 10V1000 capacitor

l All PWM output lines are protected by 220 ohm series resistor, which can easily control the LED.
