Description: The SparkFun 9DoF Sensor Stick is an easy-to-use 9 Degrees of Freedom IMU. The Sensor Stick deftly utilizes the LSM9DS1 motion-sensing system-in-a-chip, the same IC used in the SparkFun 9DoF IMU Breakout. It houses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer – nine degrees of freedom (9DoF) in a single IC!
The onboard LSM9DS1 is equipped with a digital interface, but even that is flexible. The biggest difference between the two boards, besides the slimmed down 0.9"x0.4" footprint, is the number of broken-out pins, with the Sensor Stick featuring only four for quick setup and ease of use.
The LSM9DS1 is one of only a handful of ICs that can measure three key properties of movement – angular velocity, acceleration and heading – in a single IC. By measuring these three properties, you can gain a great deal of knowledge about an object’s movement and orientation. The LSM9DS1 measures each of these movement properties in three dimensions. That means it produces nine pieces of data: acceleration in x/y/z, angular rotation in x/y/z, and magnetic force in x/y/z.
Each sensor in the LSM9DS1 supports a wide spectrum of ranges: the accelerometer’s scale can be set to ± 2, 4, 8, or 16g, the gyroscope supports ± 245, 500, and 2000°/s, and the magnetometer has full-scale ranges of ± 4, 8, 12, or 16 gauss.
Based on 4 ratings:
I have been working with it and its amaizing the easy-to-use sensor.
well designed, easy to use, very compact. I also like the design of the solder/cut pads for i2c pull-ups and address
I get its cheap, but this stick broke within a couple minutes of use. The fiberglass is no more than 0.030" thick, and I would not be surprised if a little bending load broke the joints on the chip.
The IMU has been working just fine. I do wish their was protection against over voltage and even reverse voltage as that seemed to be the only weakness experienced with my students. But that statement can apply to many other parts too. All around a good device for a very nice price.
