Description

This PCA9685 12 Bit 16 Channel Servo Shield is perfect if you want to build a robot, perhaps a hexapod or a project that requires several components that require movement. It is also ideal in controlling many LEDs with precise PWM signal and perform microprocessor has a limited number of PWM pin. For this applications, the shield of servo-motors with PWM driver is the product you are looking for. Using this shield, 16-pin PWM can be controlled with just 2 pins I2C interface.

The PCA9685 is in the new Fast-mode Plus (Fm ) family. Fm devices offer higher frequency (up to 1 MHz) and more densely populated bus operation (up to 4000 pF).

Although the PCA9635 and PCA9685 have many similar features, the PCA9685 has some unique features that make it more suitable for applications such as LCD or LED backlighting and Ambilight:

The PCA9685 allows staggered LED output on and off times to minimize current surges. The on and off time delay is independently programmable for each of the 16 channels. This feature is not available in PCA9635.
