Frequently asked questions
What element does this module drive?
It drives a 108 kHz ultrasonic atomizing transducer. Make sure the transducer's operating frequency matches 108 kHz before connecting it.
How do I power it?
Supply a DC voltage between 4.5 V and 5.0 V, such as a 5 V USB source. The module starts when power is applied, so there is no separate start control.
