Applications
Ceiling fan
A lot of electrical appliances are seen in our daily lives. In the summer, the ceiling fan is able to allow good ventilation. With wider coverage area than the ordinary fan, it is widely used in the home or at work
Based on MindMotion’s MM32SPIN030C/MM32SPIN040C microcontroller, the ceiling fan takes MM32SPIN030C/MM32SPIN040C as its main control.
