Beeper 

The EM3296 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.
