Product Brief
CAN PMU Lite is a CUAV standard power management module with built-in STM32F412 processor, supporting 10~60V voltage input and 5.2V/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 andis factory calibrated to ensure that more accurate voltage and current data can be ob-tained at different temperatures.
