GY-51 LSM303DLH module 3-axis magnetic field acceleration

The GY-51 LSM303DLH module combines a 3-axis accelerometer and a 3-axis magnetometer in one chip, the LSM303DLH, on a small breakout board. It measures acceleration and tilt as well as the Earth's magnetic field, so you can build a tilt-compensated digital compass or track orientation in robots, drones and handheld devices. It talks to Arduino, ESP32 and Raspberry Pi boards over I2C.

GY-51 LSM303DLH module Specifications

• Sensor: LSM303DLH 3-axis accelerometer and 3-axis magnetometer
• Accelerometer range: ±2, ±4 or ±8 g, selectable
• Magnetometer range: ±1.3 to ±8.1 gauss, selectable
• Interface: I2C, with separate addresses for the two sensors
• I2C addresses: 0x18 or 0x19 for the accelerometer, 0x1E for the magnetometer

GY-51 LSM303DLH module Applications

• Tilt-compensated digital compass
• Heading control for robots and rovers
• Orientation sensing in drones and RC models
• Motion, tilt and vibration detection
• Learning about IMUs and sensor fusion

What's in the Box

• 1 × GY-51 LSM303DLH module

Tip: Keep the module away from motors, magnets, speakers and steel parts, and calibrate the magnetometer by turning it slowly through all directions before use. The LSM303DLH is an older part, so use a library written for the DLH version rather than the newer LSM303DLHC, which has some register differences.
