ADXL345 iMEMS® Accelerometer, 3 Axis Sensor Evaluation Board The ADXL345 measures acceleration in three axes (X, Y, Z) and outputs digital data via either I²C or SPI interfaces. It is widely used in applications like tilt sensing, vibration monitoring, free-fall detection, and motion-based user interfaces. Its high resolution (up to 13-bit) allows it to detect very small changes in motion, making it suitable for both consumer electronics and industrial applications. Key Features 3-axis acceleration measurement (X, Y, Z) Selectable measurement ranges: ±2g, ±4g, ±8g, ±16g High resolution (13-bit) with up to 4 mg/LSB sensitivity Digital output interfaces: I²C and SPI Low power consumption: ideal for battery-powered devices Built-in motion detection functions: Tap and double-tap detection Free-fall detection Activity and inactivity monitoring Wide bandwidth range: supports various data rates for different applications Operating voltage: typically 2.0V to 3.6V Compact package: small LGA form factor suitable for space-constrained designs Common Applications Smartphones and tablets (screen rotation, motion sensing) Wearable devices and fitness trackers Gaming controllers Robotics and drones Vibration and shock monitoring systems #commonpartslibrary #developmentboard #evaluationboard #sensor

Accelerometer X, Y, Z Axis ±2g, 4g, 8g, 16g 0.05Hz ~ 1.6kHz 14-LGA (3x5) 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 formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface. The ADXL345 is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (3.9 mg/LSB) enables measurement of inclination changes less than 1.0°. Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds. Tap sensing detects single and double taps in any direction. Free-fall sensing detects if the device is falling. These functions can be mapped individually to either of two interrupt output pins. An integrated memory management system with a 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor activity and lower overall system power consumption. Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation. The ADXL345 is supplied in a small, thin, 3 mm × 5 mm × 1 mm, 14-lead, plastic package. ► Ultralow power: as low as 23 µA in measurement mode and 0.1 µA in standby mode at VS = 2.5 V (typical) ► Power consumption scales automatically with bandwidth ► User-selectable resolution ► Fixed 10-bit resolution ► Full resolution, where resolution increases with g range, up to 13-bit resolution at ±16 g (maintaining 4 mg/LSB scale factor in all g ranges) ► Embedded memory management system with FIFO technology minimizes host processor load ► Single tap/double tap detection ► Activity/inactivity monitoring ► Free-fall detection ► Supply voltage range: 2.0 V to 3.6 V ► I/O voltage range: 1.7 V to VS ► SPI (3- and 4-wire) and I2C digital interfaces ► Flexible interrupt modes mappable to either interrupt pin ► Measurement ranges selectable via serial command ► Bandwidth selectable via serial command ► Wide temperature range (−40°C to +85°C) ► 10,000 g shock survival ► Pb free/RoHS compliant #CommonPartsLibrary #IntegratedCircuit #Sensor #Transducer #Motion-Sensor #Accelerometer #ADXL345
