Beeper

The EM3080-W provides a pin (BUZZ, PIN 9) on the host interface connector that provides a PWM output

to an external driver circuit for generating audible feedback to the user to indicate statuses like power up

or good read. The PWM output is not strong enough to drive a beeper, thus a beeper driver circuit is

needed.

The following beeper driver circuit is provided for reference.
