Hey Everyone,

Anybody have any experience with this board? Bought one from Ebay without realizing it uses I2C, and for the life of me I can't find a PDF on the specs which would include addresses for each of the 3 chipsets.

Thanks!

Bendage, Nice board but not much good without a manual. I would try requesting information from the seller and just add that you can't leave good feedback if they don't provide the information needed to use the board. It has worked for me in the past. Most sellers don't like to get bad ratings. Good luck, please let us know how it turns out. Chuck

Chuck, Thanks for the reply. I bought it a year ago, but I have contacted 8 vendors currently selling it. We shall see what happens. Someone sent me specs on GY-80 but it uses 2 of 3 diff chipsets. Keep you posted... Brian

Buying frm ebay seller is ripped u off. Direct factory frm china cost US$29.99 with free shipping and without quantity. The module could be faked or counterfeited. The module will not guaranteed, will last frm one yrs to 5 yrs or more.

Here is good link:
GY-85

Scroll to bottom to see 9 DOF. The latest one is GY-86. with 10 DOF There is huge code and value code too.

Also in US, there is a robot magazine that carried everything, also made in USA too. And also including articles abt NETDUINO tooPosted ImagePosted ImagePosted Image
Arduino is selling US$18.00.

Good luck

I am using this sensor with an Arduino and this https://github.com/p...ter-calibration

 

It works, but I am not sure what the sensors output. Is the gyro really DEG/s or RAD/s or something else? Is the MAG really m/s²? See http://forum.unity3d...meter?p=1368144, too.
