SmartElex LSM303AGR Accelerometer/Magnetometer

The SmartElex LSM303AGR Accelerometer & Magnetometer digital tilt and compass sensor is a compact, high-precision module designed to measure motion, orientation, and heading in embedded and IoT projects.

It integrates a 3-axis accelerometer to sense tilt and gravity direction, along with a 3-axis magnetometer to detect magnetic fields and determine compass heading. By combining both sensor outputs, the module enables accurate orientation and navigation data for robotics, drones, wearables, and motion-aware systems.

Based on the latest LSM303AGR sensor, it communicates via I2C, works seamlessly with both 3.3V and 5V microcontrollers, and comes fully assembled on a breakout PCB with onboard support circuitry—making it easy to use, solder-free, and ready for real-world applications.
