New products: MinIMU-9 and AltIMU-10 v3

We are happy to introduce new v3 versions of our MinIMU-9 and AltIMU-10 inertial measurement units (IMUs). These sensor modules are the same compact sizes as their predecessors and have same pin-out, but they are based on ST’s newer and better L3GD20H 3-axis gyro and LSM303D 3-axis accelerometer/magnetometer. The nine independent rotation, acceleration, and magnetic measurements from these sensors provide all of the information required make an attitude and heading reference system (AHRS). In addition to this, the AltIMU-10 v3 incorporates an LPS331AP digital barometer that can be used to measure pressure and altitude.

The new revisions offer a wider magnetic sensing range and a more accurate and stable gyro, all with lower power consumption, and they include an extra pin for changing the I²C slave addresses so that two boards can be used on the same I²C bus. They should generally be usable as drop-in replacements for our previous MinIMU-9 v2 and AltIMU-10 modules—which we have put on clearance—though changes to register locations might require updates to software that is not based on our Arduino libraries.

We also have individual carrier boards available for the L3GD20H gyro, LSM303D accelerometer/magnetometer, and LPS331AP barometer if your application doesn’t require quite so much data or if you want to build your own AHRS unit.
