16-Channel 12-bit PWM/Servo Driver I2C interface PCA9685 for Arduino Raspberry Pi

16-Channel 12-Bit PWM/Servo Driver – I2C Interface

📝 Description:

If your project involves many servos, LEDs, or motors, and your microcontroller doesn’t have enough PWM outputs, this 16-Channel PWM/Servo Driver is the ideal solution. Based on the PCA9685 chip, it provides 16 independent 12-bit PWM outputs, controllable via just two I2C pins.

This I2C-controlled PWM driver features a built-in clock, meaning it runs independently of your main controller—no need for constant signals or CPU load. You can chain up to 62 modules for a total of 992 outputs, making it perfect for robotics, lighting, or automation projects.

It is 5V tolerant, so you can use it safely with both 3.3V and 5V systems, and the outputs can drive up to 6V servos or LEDs. Onboard features like reverse polarity protection, output enable, and a green power LED ensure a safe and user-friendly experience.
