Product Brief
CAN PMU lite is a CUAV standard version of the power management module, built-in STM32F412 processor, supports 10~62V voltage input and 5.4V/4A regulated output. Compared with HV_PM, it uses advanced CAN bus communication and supports standard UAVCAN protocol. PMU lite has built-in ITT temperature compensation algorithm and performs factory calibration to ensure the consistency of measurement results at different temperatures.
Product main function
1. Support 10~62V voltage input
2. Maximum passing current: maximum 90A
3. Measurement accuracy, current accuracy within 80A 0.2, voltage accuracy 0.15V
4. Regulated output: can provide up to 21W 5.2V/4A power output for peripherals
5. Power indicator LED, visually indicate Lipo voltage status
6. Future upgrades support more functions such as power consumption statistics and instantaneous power consumption push
