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.
