PCA9685 16-Channel 12-bit PWM Servo Driver – I2C Interface

The PCA9685 16-Channel PWM Servo Driver is a powerful and versatile module that allows you to control up to 16 servos or LEDs using just two I2C pins. Based on the PCA9685 chip, it provides 12-bit resolution (4096 steps) for smooth and precise control of servo motors or LED brightness. It’s perfect for robotics, RC projects, lighting control, and automation systems.

This module can be easily interfaced with Arduino, Raspberry Pi, ESP32, and other microcontrollers, making it an essential tool for projects requiring multiple PWM outputs.
