Even though this product has been retired, would you please be able to put up the Eagle board layout or Gerber files for this? I am having a bit of trouble creating the touch sensor portion using Eagle.

50 bucks for a breakout board is a little crazy (as fantastic as the MPU-9150 is).
But as far as Sparkfun prices go, I think this particular board is an exception rather than the norm; wouldn’t you say so? For example, some Sparkfun breakout boards are even cheaper than the original manufacturer-provided evaluation boards (granted an evaluation board has a bit more functionality).
Right. However, note that Pansenti’s library (linked in earlier comments) provides sensor fusion using the onboard DMP as far as I’m aware.
Well, the main advantage of the MPU-9150 is that as a system-on-chip combining all three separate sensors (accel, gyro, and mag), it makes it possible to do sensor fusion, which shifts the computation away from the external microcontroller and presumably should provide a more accurate result.
Hi Pansenti, Thanks for all the constant development on this library. Also, just curious since you added the dual support: What kind of applications are there that demand using multiple 9DOFs on the same board? (Wouldn’t they both have roughly the same output if two MPU-9150s were on the same PCB?)
Although no one has made a tutorial yet, here is something that might be useful: Pansenti has just put up an Arduino library for the MPU-9150, along with implementation of 9-axis fusion.
Link to Github repo. Link to blog page.
Great news everyone! It seems Pansenti has been gracious enough to create and Github-upload an Arduino library for the MPU-9150, including 9-axis fusion. Check the Github page for the library. Also this blog page.
Indeed. And I vote for the former of the two options - “Provide info on how to enable/use the DMP for this particular chip”. I would buy Half a dozen more of these for my present project, if I could exploit the DMP feature, which would supposedly differentiate this chip from discrete solutions like the Razor.
Another request for either code/tutorial/example of using the DMP!

All, if you should need it, you may find the bootloader HEX file for the Mega 3.3V here (original code authored by Brett Hagman):
