PCA9685 16-Channel 12-bit PWM/Servo Driver – I2C interface

The 16-Channel 12-bit PWM/Servo Driver with I2C interface PCA9685 is a versatile module designed to provide precise control over multiple PWM outputs. It’s a perfect fit for projects involving robotics, automation, lighting control, and servo motor control.

This module supports both Arduino and Raspberry Pi platforms. If you want to make a robot which has lots of moving parts or if you want to control too many LEDs with PWM outputs, then the limited PWM outputs of your microcontroller would be a big problem for you.

To overcome this problem, the only thing you should do is to get a 16-Channel 12-bit PWM/Servo Driver. You can control 16 free-running PWM outputs with 16-Channel 12-Bit PWM/Servo Driver using only 2 pins. You can even chain up 62 breakouts to control up to 992 PWM outputs.

It’s an I2C-controlled PWM driver with a built-in clock. That means you do not need to continuously send it to signal to tie up your microcontroller.

It is 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs. This is good when you want to control white or blue LEDs with 3.4+ forward voltages. 6 address select pins so you can wire up to 62 of these on a single I2C bus, a total of 992 outputs.
