PCA9685 16-Channel 12-Bit PWM Servo Driver Module (I2C Interface)

The PCA9685 16-Channel PWM Servo Driver Module is a compact expansion board designed to provide 16 independent PWM output channels with 12-bit resolution. It uses the PCA9685 driver IC and communicates through the I2C interface, allowing multiple PWM outputs to be controlled using only two communication lines.

The module is suitable for robotics, servo control, LED dimming, motor control, automation, Arduino, ESP32, Raspberry Pi, and other embedded electronics projects requiring additional PWM outputs.
