16-Channel 12-bit PWM/Servo Driver I2C interface PCA9685 for Arduino Raspberry Pi

Description

16-Channel 12-bit PWM/Servo Driver I2C interface PCA9685 for Arduino Raspberry Pi

1. 16 Channels: The PCA9685 can control up to 16 devices independently, making it suitable for applications requiring precise control of multiple outputs.

2. 12-bit Resolution: Each channel supports 12-bit PWM resolution, allowing for smooth gradations in brightness or position control (for servos).

3. I2C Interface: The PCA9685 communicates with the microcontroller over the I2C (Inter-Integrated Circuit) interface. This enables easy integration with popular development boards like Arduino and Raspberry Pi.

4. Frequency Adjustability: The PWM frequency can be adjusted between 24 Hz and 1526 Hz, allowing flexibility based on the application requirements.

5. Prescaler for External Clock: The PCA9685 allows an external clock input, and a prescaler can divide the external clock to generate the desired PWM frequency.

6. Sleep Mode: The device can be put into sleep mode to conserve power when not in use.
