GY-291 ADXL345 3-Axis Accelerometer

GY-291 ADXL345 3-Axis Accelerometer is a sensor board based on ADXL345 accelerometer integrated circuit. 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.
