PCA9685 12BIT 16 CHANNEL PWM SERVO DRIVER
PCA9685 12-bit 16-channel PWM servo driver module for controlling multiple servos or LEDs with high precision.
Category: All Categories
Tag: PCA9685 12BIT 16 CHANNEL PWM SERVO DRIVER
Description
The PCA9685 12-bit 16-Channel PWM Servo Driver is a versatile module designed to control up to 16 servos or LEDs simultaneously with precise PWM signals. Featuring 12-bit resolution (4096 steps), it allows for smooth and accurate servo movement or LED brightness control. This I2C-based module supports multiple drivers on a single bus, making it ideal for complex robotics, animatronics, and lighting projects. Fully compatible with Arduino, Raspberry Pi, and other microcontroller platforms, the PCA9685 simplifies wiring and coding for multi-servo applications.
