The ADXL345 is a small, thin, ultralow power 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is accessible through either an SPI or I2C digital interface. This makes it a mechanical necessity for mobile devices, 3D printer vibration compensation (Klipper), and tilt-sensing applications, where it can measure both static gravity and dynamic motion or shock.

▪Variable G-Force Sensitivity: The ability to switch between ±2g and ±16g is a mechanical necessity for diverse projects, allowing high resolution for slow movements or wide range for high-speed tracking and impact.

▪Intelligent Power Management: Its ultra-low power consumption scales with bandwidth, making it the ideal choice for battery-operated IoT nodes and long-term data logging.

▪Built-in Motion Triggers: Features programmable interrupts for free-fall and tap detection, allowing the sensor to "wake up" the system only when specific physical events occur.

▪Wide Compatibility: With an onboard RT9161 power chip and level shifters, it interfaces safely with both 3.3V and 5V microcontrollers, ensuring a noise-free signal for precise inclination changes.

▪High-Shock Survival: Rated for 10,000 g shock survival, this sensor is rugged enough for industrial-grade vibration monitoring and high-impact aerospace prototypes.
