PCA9685 16-Channel 12-Bit PWM Servo Motor Driver Module

The PCA9685 16-Channel Servo Motor Driver Module is a versatile I2C-controlled PWM driver designed for robotics, automation, and LED lighting projects. Ideal for Arduino, Raspberry Pi, and other microcontrollers, it lets you control up to 16 servos or LEDs using only two I2C pins. The built-in clock allows for independent, smooth, and precise PWM signals, eliminating the need for constant microcontroller updates.

Key Features and Benefits

  • Controls up to 16 servo motors or LEDs simultaneously with accurate PWM output.
  • Chain up to 62 modules on a single I2C bus for massive scalability—up to 992 PWM outputs.
  • 12-bit (4096-step) resolution ensures precise servo or light brightness control.
  • Adjustable PWM frequency up to about 1.6 kHz for flexible applications.
  • Compatible with both 3.3V and 5V systems, perfect for microcontrollers like Arduino and Raspberry Pi.
  • Integrated clock eliminates the need to generate PWM signals via the MCU.
  • Reverse polarity protection and capacitor filtering for safe and stable operation.
  • Ready-to-use 3-pin headers for quick servo and LED connections.
