16 Channel I2C PWM/Servo Driver Card PCA9685
With the PCA9685 driver card, you can add 16 extra PWM outputs to your Arduino or other microcontrollers. In this way, you can easily realize applications that use a large number of LEDs or servo motors with your PCA9685 card.
- The card has 12-bit resolution. It can operate at 3.3V and 5V logic levels.
- You can prevent too much pin occupation on your microcontroller; 12C interface is used.
- Thanks to the 6 address changing solder jumpers on it, you can use up to 62 of this card on a single I2C line.
- There is also an output sequence according to standard servo connectors.
- Thanks to the connection pins at both ends of the board, they can be connected to each other, or it allows connection and assembly in the most suitable way for your project with Arduino or other microcontrollers.
- Thanks to the terminal connection on it, V+ You can apply external supply from the line.
- There is reverse voltage protection on the PCA9685 motor driver card.
