CUAV Power Management Module Family
A power management module (PMU) combines voltage conversion, power monitoring and power management:
- Supplies adapted power to the controller, GPS and other core components
- Reports battery voltage, current and remaining capacity to the controller
- Lets the controller judge battery state and enter protection on low voltage or low capacity, keeping the flight safe

WARNING
CAN PDB is a controller carrier board. It works with V5+ / X7+ / X7+ Pro controllers and is not compatible with Pixhawk V6X v2 or the X25 series. See the CAN PDB manual.
Default package
- V5 series intelligent controller packages include the HV PM module.
- X7 series and Pixhawk V6X packages include the CAN PMU lite module.
