Summary
Provides DC motor, stepper motor, and PWM output control using the Adafruit FeatherWing board based on PCA9685 via I2C.
Description
The **Adafruit Stepper + DC Motor FeatherWing** allows control of up to **4 DC motors**, **2 stepper motors**, and **additional PWM outputs**. It is based on the PCA9685 16-channel PWM driver and TB6612 MOSFET drivers. Each motor driver has configurable slope control, initial values, and enable states. Four PWM channels (0, 1, 14, 15) are directly accessible for analog output.

Properties
- Address (i2c) – I2C address of the FeatherWing.
- PWM Frequency (Hz, default 1600) – Base PWM frequency.
- Sleep (boolean) – Enable/disable low-power sleep mode.
