- I2C-INA-BM is an ultra-precise digital power monitor based on TI INA228.
- The resistance of this conductive path is 200 μΩ typical, providing low power loss in the application.
- Support 3x I2C-INA-BM on one I2C bus in parallel.
- No calibration required, Flight controller with ArduPilot fw can easily get accurate current & bus voltage readouts via I2C bus.
