PCA9685 16-Channel PWM Servo Motor Driver Module – I2C Controlled for Arduino, Raspberry Pi, and Robotics Projects

⚙️ PCA9685 16-Channel PWM Servo Motor Driver Module – I2C Controlled for Arduino, Raspberry Pi, and Robotics Projects

The PCA9685 16-Channel Servo Motor Driver Module is a powerful I²C-based PWM controller that allows you to independently control up to 16 servo motors or PWM outputs using just two I2C pins from your microcontroller. It’s perfect for applications requiring multiple servo motors such as robotic arms, hexapods, biped robots, RC vehicles, and animatronics.

Powered by the reliable PCA9685 chip, the module provides 12-bit resolution PWM control and can drive standard servos, LEDs, or other PWM-controlled devices with precise timing. It includes a dedicated external power input (via screw terminal) to supply enough current for all connected servos, and an onboard 3.3V regulator to safely interface with both 3.3V and 5V logic systems.
