CUAV Power monitoring module family
The power monitoring module (PMU) includes transformer and power monitoring and management functions.
The main function:
- Provide adaptive power supply for core components such as autopilot and GPS
- Provide information such as battery voltage, current, remaining power, etc. to the autopilot.
- The autopilot determines the battery status through the battery information provided by the power monitoring module. When the voltage is low or the battery is low, it enters the protection state to ensure flight safety.
