FAQ

Q: Why choose an automotive-grade accelerometer for a drone?
A: Automotive-grade (AEC-Q100) qualification provides documented reliability: the sensor has been tested to survive 1,000 temperature cycles (−40 to +125°C), 1,000 hours of high-temperature operating life, ESD to 2 kV HBM, and mechanical shock to defined standards. For professional drone manu

Q: Is the AIS328DQTR pin-compatible with other ST accelerometers?
A: No. The AIS328DQTR uses a QFN-24 (4×4 mm) package, while consumer LIS-series accelerometers use LGA packages (LGA-12 2×2 mm, LGA-16 3×3 mm). The QFN package has exposed leads for visual solder joint inspection — a reliability feature at the cost of larger footprint. Not a dro

Q: Does the AIS328DQTR support I²C?
A: No — the AIS328DQTR is SPI-only (3/4-wire). This is by design for automotive applications where deterministic timing and EMC immunity of SPI are preferred over the simplicity of I²C. If you need I²C, consider the LIS3DH or LIS2DH12 consumer sensors.

1. Product Overview

The AIS328DQTR is STMicroelectronics' AEC-Q100 qualified automotive-grade 3-axis MEMS accelerometer with selectable full scales ±2/±4/±8 g, 16-bit resolution, and SPI digital interface. Designed for the demanding automotive environment (vibration, temperature extremes, EMC), it brings automotive-level reliability and extended temperature range (−40°C to +105°C) to drone applications where sensor failure is not an option. The QFN-24 (4×4 mm) package provides robust mechanical attachment and excellent thermal performance, making it suitable for professional-grade drone autopilots, heavy-lift industrial UAVs, and safety-critical flight control systems requiring proven reliability. In the drone ecosystem, the AIS328DQTR finds its niche in: (1) prof
