Power Module
The main function of the power module is to output different voltages and currents to provide stable and reliable power for various equipment, to ensure the normal power supply of each component, and to output accurate battery information to the ground station in real time. Some power supply modules are also integrated with an intelligent controller baseboard, which can optimize wiring, save internal structure space, contribute to product miniaturization, improve integration level, and reduce cost.
PMU 2 Lite is a power management unit module for unmanned system devices. It features a built-in STM32H5 processor, runs self-developed M4C architecture software, and uses the ITT3 temperature impedance tracking algorithm. It can accurately measure the voltage and current of unmanned systems in real time and supports 20V ~ 70V voltage and 220A current. It communicates via CAN bus. Each module has been factory pre-calibrated to ensure good consistency and accuracy.
The CAN PDB is a multifunctional baseboard for the controller CORE module; it provides a wide range of interfaces and integrates power module and power distribution board (PDB) functions. It supports an input voltage range of 14–62V and delivers a continuous operating current of up to 110A. Utilizing a proprietary ITT algorithm, it offers power monitoring with a resolution of 0.1A and 0.05V, achieving measurement precision comparable to that of precision instruments. It features ten power output solder pads and provides regulated 5V/6A and 12V/4A outputs to power external devices. It supports the CORE modules for V5+, X7+, and X7+ Pro controllers.
The CAN PMU is a power management unit module designed for unmanned systems. It features an integrated STM32F4 processor running the CUAV ITT algorithm, enabling real-time, accurate measurement of system voltage and current. It supports input voltages of 6–62V and currents up to 110A, while providing a 5.4V/5A output (5A continuous; 8A peak for 120s) to power the controller. Utilizing CAN bus communication and supporting the standard DroneCAN protocol, each unit undergoes factory calibration to ensure excellent consistency and high accuracy.
The CPDB Pro is an onboard device that integrates voltage and current sensing with power distribution capabilities. It supplies power to the controller while providing voltage and current signals, and features two independent output ports for 5V and 12V power. Suitable for quadcopters as well as hexacopters and octocopters (the solder pads allow for two power wires to be attached), the device’s independent 5V output can also power servos when used in fixed-wing aircraft, unmanned ground vehicles, or unmanned surface vessels, resulting in cleaner and more convenient wiring.
The CAN PMU Lite is a CUAV standard power management module featuring a built-in STM32F412 processor; it supports an input voltage range of 10–60V and provides a regulated output of 5.2V/4A. Unlike the HV_PM, it utilizes advanced CAN bus communication and supports the standard DroneCAN protocol. The CAN PMU Lite incorporates an ITT temperature compensation algorithm and undergoes factory calibration to ensure accurate voltage and current data across varying temperatures.
