Frequently Asked Questions
- Q: What is the PCA9685 16 Channel PWM Servo Driver used for? A: The PCA9685 16 Channel PWM Servo Driver is used to control multiple servos or LEDs when your microcontroller lacks sufficient PWM output pins. It allows you to manage up to 16 free-running PWM outputs using only two pins, making it ideal for projects requiring multiple servo controls or LED configurations.
- Q: Is the PCA9685 compatible with both Arduino and Raspberry Pi? A: Yes, the PCA9685 is compatible with both Arduino and Raspberry Pi platforms. It utilizes I2C communication, which is supported by both types of microcontrollers, allowing for easy integration into your projects.
- Q: How many servos can I control with the PCA9685? A: You can control up to 16 servos simultaneously with the PCA9685 using its built-in PWM outputs. Furthermore, you can chain multiple PCA9685 boards together to control up to 992 PWM outputs, making it highly scalable for larger projects.
- Q: What is the resolution of the PWM outputs on the PCA9685? A: The PCA9685 provides a 12-bit resolution for each PWM output. This translates to approximately 4 microseconds of resolution at a 60Hz update rate, allowing for precise control over servo positions and LED brightness.
- Q: Do I need to send continuous signals to the PCA9685? A: No, the PCA9685 features a built-in clock that allows it to run independently once configured. Unlike other PWM drivers, you do not need to continuously send signals from your microcontroller, freeing up resources for other tasks.
