CUAV PMU 2 Lite High-Precision Power Management Unit 20–70V Wide Voltage Input, DroneCAN for UAVs & Unmanned Systems

PMU 2 Lite Power Manager Unit is a high-precision power management module designed for UAVs and unmanned systems, featuring 220A high-current detection and 20V–70V wide voltage input compatible with 16S batteries.

It adopts non-contact, coreless busbar current sensing technology and runs on a self-developed M4C architecture powered by an STM32H5 Cortex-M33 processor (250MHz). With the ITT3 temperature impedance tracking algorithm, PMU 2 Lite delivers outstanding measurement accuracy of ±0.05V / ±0.1A across wide temperature and load ranges. Factory pre-calibrated for plug-and-play use, it supports DroneCAN / CAN bus communication, offers 5V or 15V regulated outputs, and features an aluminum alloy housing for efficient heat dissipation, making it an ideal UAV power management unit for ArduPilot and PX4 platforms.
