Vszerda GY-51 LSM303 3-Axis Compass Accelerometer Module

SKU CH-B6SK-FT7ZE

A compact module combining a 3-axis accelerometer and magnetometer for orientation sensing over I2C

  • 3-axis compass and accelerometer in one module
  • 3-5V supply works with common logic levels
  • IIC interface simplifies wiring to microcontrollers
  • GY-51 board integrates LSM303 sensor for orientation sensing

GY-51 LSM303 3-Axis Compass Module

The Vszerda GY-51 LSM303 module combines a three-axis accelerometer and a three-axis magnetometer on a single board. It operates from a 3 V to 5 V supply and communicates through an IIC interface. The board is intended for hobbyists and engineers adding orientation sensing to microcontroller projects.

3-5 V IIC Interface for Microcontroller Integration

The module works with 3 V to 5 V logic levels and uses a standard IIC bus, allowing direct connection to common development boards without level shifting. Projects that require a different communication protocol or a higher-voltage supply will need a separate solution.

Questions about this item

What does the 3-axis compass and accelerometer actually give me in a project?

The module combines a 3-axis magnetometer with a 3-axis accelerometer, so you can measure both heading and tilt in one board for orientation or navigation tasks.

How does the IIC interface limit the way I connect the module?

The board communicates over a standard I²C bus, meaning it shares two wires with other devices and its address is fixed, so you cannot run multiple modules on the same bus without a multiplexer.
