PCA9685 16-Channel 12-Bit PWM Servo Driver is an I2C-controlled module for PWM and servo control. It provides 16 PWM channels with 12-bit resolution and a built-in clock. The module supports daisy-chain operation for multiple boards on the same I2C bus. It is designed for applications that need more PWM outputs from limited microcontroller pins. This module includes an internal power-on reset, noise-filtered SDA/SCL inputs, and low standby current.
