GY-291 ADXL345 Digital 3-Axis Accelerometer Module with Pin Header (Tilt/Gravity Sensor – New Loose Chips)

Description

Description

The GY-291 ADXL345 is a high-precision, low-power, 3-axis accelerometer module capable of measuring acceleration with a selectable range of up to ±16g. Built around Analog Devices’ renowned ADXL345 IC, this module is designed for tilt sensing, motion detection, gravity measurement, and vibration analysis in both consumer and industrial applications.

Unlike many basic accelerometers, the ADXL345 features 13-bit resolution at ±16g, allowing it to detect inclination changes as small as 0.25°. The module supports both I²C and SPI digital interfaces, making it compatible with a wide range of microcontrollers including Arduino, STM32, ESP32, Raspberry Pi, and other 3.3V or 5V logic systems (with onboard voltage regulation).

This version comes with pre-soldered pin headers for easy breadboard or PCB mounting. The “New Loose Chips” designation ensures you receive fresh stock with genuine ADXL345 ICs, not reclaimed or counterfeit components. Whether you are designing a motion-controlled robot, a vehicle data logger, a wearable device, or an industrial tilt sensor, the GY-291 delivers reliable, noise-resistant measurements in a compact form factor.
