This is a mini ultrasonic levitation device that can suspend foam balls.
The device consists of a single chip microcomputer,a driver chip and two ultrasonic probes.
Mainly used for students or DIY electronics enthusiasts to learn about ultrasonic standing wave suspension.
2.Feature:
1) It comes with a DC power interface for easy charging.
2) It has a program download interface and is easy to use.
3) It supports long-term suspension,the motherboard will be slightly hot.
4) It has a power indicator and an ultrasonic suspension indicator,and you can see the working status of the product by observing the indicator.
3.Parameter:

2) Input Voltage:DC 12V
3) Input Current:70mA(Max)
4) LED (red):Power Indicator
5) LED (green):Ultrasonic levitation indicator
6) Probe Spacing:22mm
7) Work Temperature:-25℃~85℃
8) Work Humidity:5%~95%RH
9) Size(Installed):62*42*42mm
4.Working Principle:
Ultrasonic standing wave suspension is that there is a certain distance between the ultrasonic transmitting end and the reflecting end (or another transmitting end) (called the resonant cavity distance).
The transmitted wave and the reflected wave (or another acoustic wave) are continuously superimposed to form a standing wave. The acoustic wave force on the object at the standing wave node overcomes the effect of gravity and finally achieves the effect of suspension.
