- The PCA9685 IIC module is a 5V-compliant device that allows you to easily control it with a 3.3V microcontroller. It supports output voltages up to 6V, making it perfect for driving white or blue LEDs with a forward voltage of 3.4V or higher. - Enjoy precise control with the 2-bit resolution for each output, providing approximately 4 microseconds of resolution at an update rate of 60Hz, ideal for servo applications. - The module features four groups of 3-pin connectors, enabling you to connect up to 16 servos simultaneously. Note that servo plugs are slightly wider than 0.1 inches, allowing for stacking up to 4 adjacent plugs on 0.1-inch hole female headers. - This 16-channel PWM module simplifies your setup by utilizing just two pins to control 16 free-running PWM outputs. With an additional 6 address selection pins, you can connect up to 62 driver boards on a single I2C bus, enabling a total of 992 PWM outputs. Use cases include: 1. Robotics: Control multiple servos for precise movement and coordination of robotic arms and legs. 2. LED Lighting: Create dynamic lighting effects in stage productions or home decorations by controlling numerous LEDs simultaneously. 3. Model Cars: Achieve smooth throttle and steering control in remote-controlled cars, enhancing performance and user experience.
