PCA9685 PWM Servo Motor Driver (Compatible with Raspberry Pi and Arduino)

You want to build a robot, maybe a hexapod or maybe a project requiring several components that require movement. Or just control many LEDs with PWM accurate signal and realize that the microprocessor has a limited number of PWM pins. In this case, the PWM servo motor driver is the product you are looking for.

Using this chip, you can control 16 pin PWM with only 2 pins. In addition, up to 62 cards can be inserted, giving access to 992 PWM outputs.

Technical specifications:

• It is controlled by I2C, having an internal clock.
• It can be controlled from a 3.3 V or 5 V microcontroller, providing safe 6V output (ideal to control white or blue LEDs with 3.4 V +)
• Adjustable PWM frequency up to 1.6 KHz
• Exit enable pin to easily deactivate all outputs.
• Supply voltage: 2.3 - 5.5 V
• Temperature: -40 +85 Celsius
