The CJMCU PCA9685 16-Channel PWM/Servo Controller Module is a highly versatile and efficient solution for controlling up to 16 PWM outputs independently over an I2C interface. Powered by the robust PCA9685 chip, this module offers 12-bit resolution per channel, allowing for 4096 levels of programmable brightness or position control.

Designed for applications such as servo motor control, RGB/RGBA LED backlighting, LED displays, and LCD backlights, the PCA9685 module features a built-in clock, eliminating the need for continuous communication to refresh outputs. It supports Fast-mode Plus (Fm+) I2C communication up to 1 MHz, making it ideal for high-speed and dense data environments.

Thanks to its 5V-tolerant inputs, it can safely interface with both 3.3V and 5V microcontrollers, making it perfect for Arduino, Raspberry Pi, ESP32, STM32, and other platforms.

Key Features:

• 16 independent PWM channels, 12-bit resolution (4096 steps)
