IMU Digital Combo Board - 9 Degrees of Freedom L3G4200/LSM303



This is a simple breakout for the LSM303 accelerometer;magnetometer and the L3G4200 gyro. With this board, you get a full 9 degrees of freedom. The sensors communicate over I2C. If you need a simple and tiny board that gives you 9 degrees of freedom, this would be a good choice.


  • Tiny!
  • One mounting holes
  • LSM303 accelerometer
  • LSM303 magnetometer
  • L3G4200 gyro
  • 3.3V input
  • I2C interface


This IMU has been tested and flown with TWOG.

In the firmware section of the airframe add the following entries

		<subsystem name="imu" type="pololu"/>
		<subsystem name="ahrs" type="float_dcm"/>

You can define the ACC rate using the command bellow:

	<subsystem name="imu" type="pololu">
	 <define name="LSM303_ACC_RATE" value="LSM303_RATE_100"/>  <!--50,100,400,1000 -->
