Description
The Matek CAN-L4-BMis an ultra-precise digital power monitordesigned for seamless integration with ArduPilotand DroneCANprotocols. Based on the INA239 85-V Power Monitor IC, this device offers exceptional accuracy for monitoring battery voltageand currentin real-time, without requiring calibration. With a current sensing rangeof up to 204.8Aand voltage sensingup to 85V, it allows for continuous monitoring of your system’s power consumption, providing vital data for battery managementand power optimization. The low-resistance conductive pathensures minimal power loss, making this power monitor an essential tool for drones, robotics, and other power-sensitive applications. Its easy integration with flight controllersvia DroneCANand UARTmakes it ideal for users looking to efficiently monitor their system’s power health.
