- **Compass Strategy:** External IST8310 magnetometer via connector
- **Domain:** Aerospace
- **Manufacturer Name:** STMicroelectronics
- **Manufacturer Part Number:** STM32H743VIT6
- **Selected IMU:** ICM42688
- **IMU Noise Comparison:** BMI270: Accelerometer noise ~90 μg/√Hz; Gyroscope noise ~0.007 °/s/√Hz. ICM42688: Accelerometer noise ~75 μg/√Hz; Gyroscope noise ~0.004 °/s/√Hz. Overall, ICM42688 offers lower noise performance.
- **Board Outline Dimensions Including Margin:** 46.0 mm x 46.0 mm
