1. 16-Channel PWM Servo Driver with Cascade Support: The PCA9685 module supports up to 16 channels with 12-bit PWM resolution and can be cascaded to control a total of 992 servos, making it ideal for large-scale robotic projects and automation systems 2. Efficient Control with Minimal I/O Usage: With just 2 pins, the PCA9685 can independently control 16 servos, ing up valuable I/O resources on your microcontroller for other functions and optimizing your project setup 3. Wide Voltage Compatibility: The module is 5V compatible, which means you can also use a 3.3V microcontroller to control and ground drive to a 6V output 4. Optimized Communication and Performance: Utilizing I2C communication and a built-in PWM driver and clock, this module reduces the load on your microcontroller, allowing it to run smoothly without continuous signal transmission
