Worth Checking Out: Affordable Dual Axis Gyro

Image00392
If you’re designing a robot and are considering adding a gyro, then you might want to take a look at the new dual axis IDG300. Yes, that isn’t a typo. The IDG-300 is actually a dual axis gyro chip in a 3.3V leadless IC package. The chip was originally designed for image stabilization applications, but we’re guessing that it will be a natural fit for other applications, especially robotics.





The gyro chip, developed by InvenSense, Inc. in Santa Clara, Ca. is packaged in a 40 pin QFN format (6 x 6 x 1.5 mm). The gyro is being marketed by Spark Fun Electronics both as individual chips, and pre-mounted on their ‘Gyro Breakout’ board configuration.


According to the manufacturers datasheets, the new gyro chip has integrated low-pass filters, operates from a single 3V supply, and is based on a unique design that provides high cross axis isolation.

What do we really like about it? It appears to offer excellent performance with a very small form factor. And, best of all, it’s cheaper than any other comparable gyro we’ve found so far. At the chip level, considering that it’s dual axis, the cost per axis is around $25 or so.


We’re not quite ready to try it ourselves yet, but do plan to attempt to add one to a bipedal robot in the Robots Dreams labs before the end of this summer. If you have any experience with the chip, or try to implement it, let us know how it works out.

  1. I am looking at implementing/testing the performance of this chip but also need a single axis z axis gyro. Does anyone have any info on some that would be at the same rate as these?
