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.

Nice to be able to use other batteries in field, but cautious because of the failure, I’ve decided to use only on freestyle type flying where recovery is possible, but I don’t use it over water etc because it can’t be trusted now
