I have to be honest; i tried to kept this project as a little secret to void people waiting for it, so i have plenty of time to prototype. Not to mention that everything was running very slow because the school and we were moving the business to another location.I would like to give special thanks to Chris Anderson, Nathan Seidle (from SparkFun) and specially to William Premerlani, we've spent a great time together trying to adapt the code into Arduino Environment, a great experience for me (absolutely). Thank you Bill!The ArduIMU V2 is intended to be used for learning and general robotics, also will set the starting point for next incoming IMU based ArduPilot's (at the end of this year) and lot more! The code is based on the very well known Arduino Environment and is Open Source (of course!).The hardware consists on 3 axis accelerometers/gyroscopes, dual power regulator (3.3v and 5v), GPS port, an Atmega328@16mhz and a lot of status LED's.The code uses Direction Cosine Matrix code (By Bill Premerlani) and some other stuff extracted from ArduPilot (developed by me). You can read more about DCM here.The mass production is not clear yet, but the sensors can be purchased now from SparkFun or from our store. For now i will assemble just a few boards (ready to use) and sell them the next week (controller board with sensors) for around 100 bucks, sorry... For around $99 dlls. =) But being honest i will have to increase tiny bit the price to keep the DIYdrones store alive! Moving the business was kinda expensive.About the boards color, i will kindly ask Nate to change the color to blue because I'm unable to match his red (mine is more like orange). All the incoming boards from us will be blue anyway. =)The code will be released next week with the hardware. Please be patient. Thank you!Here is a demo video:
Sorry for the wait, i still have some problems with labview and the conversation between DCM to Euler angles is not working perfectly. I will solve it in the next days!
In other words you have to interface with another system like your PC or standalone microcontroller. This product can be used in ArduPilot, but there's no code for that yet.
Jordi,
I am excited along with the others about getting the ArduIMU and the uBloxGPS but what do we need to interface to the RC servos for aircraft control - I have the basic ArduPilot board but you have indicated that you will come up with a shield design or something for that configuration. We are unsure what you are using for the total aircraft control system. Thanks so much for all your efforts!

Space nut: We don't intend to use the IMU to replace the thermopiles on ArduPilot. It may be doable, but that's not our focus: we're putting our energies behind making it the core of ArduPilot Mega, which is built from the ground up around the IMU.
Yes, the Sparkfun uBlox is the same as the one we use, but you'll need our adapter and you'll have to program the GPS module yourself. It's kind of a pain, but here are instructions.

You can download the current development here:

If you have the IMU in your hands just plug the FTDI cable, load the arduino code and open the labview station using the right serial port and enjoy!
