Key Features
Dual-Sensor Functionality:
Accelerometer: Measures 3-axis linear acceleration with selectable ranges (±2g, ±4g, ±8g) for detecting motion, tilt, and vibration.
Magnetometer: Senses 3-axis magnetic fields with 7 adjustable ranges (±1.3 to ±8.1gauss), enabling accurate compass heading and orientation calculations.
Digital Precision:
Built-in 12-bit analog-to-digital converter (ADC) provides 16-bit digital output for high-resolution data (e.g., 0.061mg/LSB for accelerometer at ±2g range).
Supports I2C communication protocol (standard mode, 100kHz) for seamless integration with microcontrollers and single-board computers.
Reliable Hardware:
Compact 14.5mm×20.5mm PCB with gold-plated traces and machine-welded components to ensure stable signal transmission and long-term durability.
Internal low-drop regulator allows operation from 3–5V power sources, compatible with both 3.3V and 5V systems.
Configurable Performance:
Adjustable measurement ranges and data rates via I2C registers, enabling optimization for power efficiency (low-data-rate modes) or high-speed motion capture.
Built-in temperature compensation for consistent accuracy across operating temperatures (typical industrial range: -40°C to +85°C, not explicitly listed but standard for LSM303DLHC).
