The Servo Driver PCA9685 PWM I²C 16 Channel 12-bit Module is a powerful and flexible PWM controller designed to expand the number of PWM outputs available to your microcontroller. Based on the PCA9685 chip, this module communicates over the I²C bus, allowing you to control up to 16 channels of PWM or servo signals using just two I²C pins (SDA and SCL).
With 12-bit resolution (4096 steps) per channel, the PCA9685 provides smooth and precise control for servos, LEDs, motors, or other PWM-compatible devices. It is compatible with Arduino, Raspberry Pi, ESP32, STM32, and other microcontroller platforms, making it ideal for robotics, multi-servo installations, lighting effects, and automated systems. A dedicated 5V power input for servos helps isolate load power from the logic supply.
