New IMU from Sparkfun; soon to be an AHRS with DIY Drones

Posted by Chris Anderson on December 31, 2009 at 9:30am

Sparkfun has just released an "9DoF" Razor IMU board ($125) with an Atmega328, three flat gyros, a three-axis accelerometer and a three-axis magnetometer (no GPS input). This is basically similar to the ArduIMU+, but designed for indoor use or other places where GPS is not available or desirable. Because the Atmega runs at 16 Mhz, it's Arduino compatible. We've been working with them on this board, and will be converting the ArduIMU+ code to work with it soon; it will be available on the Sparkfun site and here. Stay tuned!

    If compass is built with IMU, it's will be a problem when placing IMU on UAV.

    Bravo Jordi, Bravo !

    Jordi, Chris,

    Need a hand on getting ArduIMU code to run on this?

    Angus, that's why I put "9DoF" in quotes. It's not technically accurate, but it's the terminology they used and is become accepted. I think we just have to hold our nose and accept it.

    Caleb, GPS *connector* built into ArduPilot Mega's IMU, with GPS data integrated into its code. We'll be using the exact same uBlox you bought.

    Wow!! Forget the IMU, I want to know more about the new dimensions that have been discovered!!

    -->NO<--, the GPS will not be integrated on the Ardupilot board, it will use uBlox as the ardupilot v1... Sorry for the confusion.

    Did i read that right? GPS built into ardupilot? oh no, after i already bought the ublox! i hoped that gps would be something that was user controlled not factory implemented.

    Correction the board will have 8Mhz (Arduino compatible too), I asked Nathan to change it for better performance at 3.3V.

    Great achievment. Let's hope the magnetometer is not to sensitive to electric motor induction. If not, this is wooo hooo.
