Reference to a PWM instance.

The period field is used by the set_brightness function of the LED API.
Its value should at least be greater that 100 nanoseconds (for a full
brigtness granularity) and lesser than 50 milliseconds (average visual
persistence time of the human eye). Typical values for the PWM period
are 10 or 20 milliseconds.

This property is required.
