10 DOF IMU Sensor Module LSM303 + L3GD20 – I2C Interface

Description

Description

The 10 DOF IMU Sensor Module integrates a 3-axis accelerometer, gyroscope, and magnetometer on a single board for comprehensive motion and orientation sensing. It combines the LSM303DLHC accelerometer/magnetometer and L3GD20 gyroscope to provide multi-axis measurements for robotics, navigation, and embedded systems. The module operates at 35 V with onboard voltage regulation and communicates via I2C, compatible with 3.3 V and 5 V logic levels. Its compact 33 23 mm FR4 PCB design supports easy integration into development and educational projects, with Adafruit library support for rapid software deployment.

Please note that the board doesn’t come with BMP180 sensor
