Power Monitor MATEKSYS i2C-INA-BM (Ultra-Precise)

Product detailed description

Power Monitor MATEKSYS i2C-INA-BM (Ultra-Precise) 

MATEKSYS I2C-INA-BM is an ultra-precise digital power monitor designed to accurately measure battery voltage and current in RC, FPV and UAV power systems. Based on the TI INA228 power monitor IC, it communicates via I2C and provides accurate readings to compatible flight controllers without requiring calibration.

Features:
- Ultra-Precise Power Monitoring: Provides accurate real-time measurement of battery voltage and current for reliable power system monitoring
- Low Power Loss: Its ultra-low-resistance current path minimizes voltage drop and power loss during operation
- No Calibration Required: Allows ArduPilot-compatible flight controllers to obtain accurate current and bus voltage readings without manual calibration
- I2C Connectivity: Communicates with the flight controller through a simple I2C interface for clean and reliable digital data transmission
- Multiple Monitor Support: Up to three I2C-INA-BM boards can operate in parallel on the same I2C bus using different addresses
- High-Voltage Monitoring: Suitable for high-voltage battery systems used in large RC models, UAVs and other demanding applications
- Compact Design: The lightweight, compact board is easy to integrate into space-constrained power systems
- ArduPilot Integration: Designed for direct compatibility with ArduPilot firmware and provides dedicated configuration parameters for battery monitoring
