# CAUV CAN PMU

CAN PMU® is a high-precision power module developed by CUAV®. It uses the UAVCAN (opens new window) protocol and runs the CUAV ITT compensation algorithm, which enables drones to get the battery data more accurately.

CAN PMU

It is recommended for use in large commercial vehicles, but might also be used for research vehicles.
