Implements support for the PCA9685 16-channel PWM controller over I2C, enabling [servo] and [output_pin] configurations for PWM and digital outputs. Supports configurable frequency (default 50Hz), I2C addressing, global MODE2 settings (invert_output, totem_pole), and per-pin software inversion. Designed primarily for applications like pick-and-place machines with servo-driven component feeders. Includes documentation and example configuration.
