GY-291 ADXL345 Accelerometer Module – Triple Axis Digital Gravity Sensor (3-Axis) for Arduino, Robotics, and Motion Detection Projects
The GY-291 ADXL345 Accelerometer Module is a high-resolution, low-power 3-axis digital acceleration sensor designed for accurate measurement of motion, tilt, and vibration in embedded systems. Built around the ADXL345 chip from Analog Devices, this module is capable of sensing acceleration in the X, Y, and Z axes with up to 13-bit resolution, making it ideal for a wide range of motion-sensing applications.
The ADXL345 supports both I2C and SPI digital communication interfaces, offering flexibility for integration with Arduino, Raspberry Pi, ESP32, STM32, and other microcontrollers. It can measure both static acceleration (gravity) and dynamic acceleration (motion or shock), with a selectable measurement range of ±2g, ±4g, ±8g, or ±16g.
The GY-291 breakout board is compact, lightweight, and features clearly labeled pin headers for easy prototyping and PCB mounting. It’s commonly used in robotics, smartphones, step counters, drone stabilization, and gesture-based control systems.
