A new 9 axes inertial sensor from ST

ST extends it's gyro line with a new 9 axes IC - LSM333D.


1. 3 axes gyroscope with ±250 to ±2000dps selectable rotational acceleration full-scale range;

2. 3 axes accelerometer with ±2g to ±16g selectable linear acceleration full-scale range;

3. 3 axes compass with ±2 to ±12gauss selectable magnetic full-scale range;

4. LSM333D includes a built-in temperature sensor and smart power management for longer handset battery life;

5. The module allows the choice of either I2C or SPI connection to the main system controller.

6. The LSM333D is available in a 3.5 x 6 x 1mm package, and will soon enter volume production in the 4 x 4 x 1mm package.

Here's the datasheet of the LSM333D in a 3.5x6x1mm. package - http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERA...

Waiting impatiently for the first samples for testing.

Best regards

That is awesome!

shame that this has not on board a sensor fusion algorithm as MPU 9150

In most cases such an algorithm hinders writing own one. Also the estimated price is times lower. There's no info about the mechanical resonant frequency yet, but if it is higher than 20-30kHz, this IC could become my favorite.

+1 on the on-board sensor fusion sometimes being a hinderance.  An AHRS algorithm written for a smartphone may not be so good for a UAV...  I would be much happier with good sensor properties (accuracy, linearity, vibration resistance, temperature compensation) than a motion solution written for a handheld device.

ok you convinced me, wait first samples

Dear Friends,

if check my new design VR BRAIN the evolution of MP32F4 for RTF and OEM application is yet developed for support that  sensor. We start a join venture with ST LAB in Italy where produce that component only 20 km far from VirtualRobotix Lab :)


Stay tuned . In my design i don't use only this great component ..

Hi Roberto,

Do you have any info about the schedule of the LSM333D ? I'm still waiting L3G3250A ...more than an year!!!!!

Comment by Roberto Navoni on May 31, 2012 at 11:46pm

Hi Nick,

in my last meeting in ST they schedule to release to my company LaserLab for test in 15 days 10 sample of chip for mounting for 10 sample of VR BRAIN.

For the gyro L3G3250A i don't have info because isn't my design i can ask.

I'm waiting also a special revision of st barometer that could be better of bmp and similar to MS .

I doing update to the project http://www.virtualrobotix.com/profiles/blogs/new-multipilot-for-rtf...

Join www.virtualrobotix.com for update .
