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.
- 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 --> </subsystem>
