Introducing the MATEKSYS Ultra Precise I2C Power Monitor – INA-BM, powered by the acclaimed TI INA228 chip for unmatched accuracy and reliability in digital power monitoring. Engineered to minimise power loss, with a low typical resistance of just 200 μΩ. It can be used to monitor both voltage (up to 85V) and current (max 204A).
Communication with the I2C-INA-BM is made simple through the I2C interface, which allows for easy integration with microcontrollers and other devices. The module’s address can be selected using the onboard jumper, providing flexibility in multi-device setups. Up to three units can be used in parallel for comprehensive monitoring.
Enjoy hassle-free operation with no calibration needed and seamless compatibility with ArduPilot firmware for precise current and bus voltage readouts.
Compatible with ArduPilot firmware only.
