PCA9685 16-Channel IIC Interface 12-Bit PWM Servo Motor Driver Board

Experience the ease of I2C communication with our PCA9685 16-Channel IIC Interface 12-Bit PWM Servo Motor Driver Board. This board eliminates the need for continuous signal transmission from your microcontroller, thanks to its built-in PWM driver and clock, distinguishing it from the TLC5940 series.

5V Compatibility and 6V Output Safety

Our board is 5V compatible, allowing you to control it using a 3.3V microcontroller and safely drive outputs up to 6V. It also supports the control of white or blue indicator lights with voltages exceeding 3.4V+.

Addressable Pins for Broad Expansion

The board comes with six address selection pins, enabling you to connect up to 62 driver boards to a single I2C bus. This results in a total of 992 PWM outputs, making it perfect for large-scale projects that require substantial resources.

Adjustable Frequency PWM Output

Our board provides approximately 1.6KHz adjustable frequency PWM output, ensuring precise control and smooth operation across various applications.

High Resolution and Configurable Output Modes

Expect outstanding performance with the board's 12-bit resolution output, specifically engineered for stepper motors. It delivers a remarkable 4us resolution at a 60Hz refresh rate and allows you to configure the output modes as either push-pull or open-drain, catering to different device types.
