Accelerometer Gyro Sensor Module GY-LSM6DS3

Accelerometer Gyro Sensor Module GY-LSM6DS3

The LSM6DS3 is a system-in-package combining a 3D digital accelerometer and a 3D digital gyroscope. It operates at 1.25 mA in high-performance mode (up to 1.6 kHz ODR) while supporting always-on low-power features for an optimal motion experience. The module provides full-scale acceleration ranges of ±2/±4/±8/±16 g and angular rate ranges of ±125/±245/±500/±1000/±2000 DPS. Minimal connections include power and I²C pins for communication. Ideal for tilt, motion, and tap sensing in robotics, IoT, and consumer electronics. Note: This is a 3.3V device—supplying >3.6V may permanently damage it. Use a logic level shifter if interfacing with 5V systems.

  } else {
    Serial.println("FAILED.");
    IMU.end();
    while (1);
  }
  Serial.println();
}

void loop() {
  char buffer[8];
  float ax, ay, az; // accelerometer
  float gx, gy, gz; // gyroscope
