PCA9685 16-Channel 12-bit PWM Servo Driver I²C Module for Arduino/ESP Projects

Expand PWM outputs for servos, LEDs, motor control and more


16 independent PWM channels • I²C control • 12-bit precision

perfect for servos, LEDs, robotics and embedded projects.

Description

This PCA9685 I²C PWM driver module provides **16 channels of 12-bit** PWM control using the I²C interface, making it ideal for expanding the PWM capabilities of microcontroller boards like **Arduino, ESP8266, ESP32, Raspberry Pi and similar boards**.

The board allows precise control of servos, LEDs, lamps, and other devices requiring PWM signals — without burdening your MCU’s timers or pins. The built-in PWM controller handles up to **4096 steps** of PWM resolution on each channel.

This module is perfect for robotics, multi-servo rigs, lighting arrays, automation projects and any situation where you need more PWM outputs than your controller board can provide.
