PCA9685 PWM Controller Servo Driver

16-Channel 12-Bit PWM I²C Interface — AU Stock

Overview

The PCA9685 is a highly integrated 16-channel PWM controller designed for precise servo and LED control via the I²C bus. Ideal for Arduino, Raspberry Pi, and other microcontroller projects, this module provides 12-bit resolution for smooth, accurate output. With programmable brightness, group dimming, and support for up to 62 devices on a single bus, it’s the perfect solution for robotics, lighting effects, and automation systems.

Key Features
