Kootek® Arduino GY-521 MPU-6050 Module 3 axial gyroscope accelerometer stance tilt module

Hardware Setup

Pin Connections

MPU6050	Arduino UNO or FIO
VCC	3.3V
GND	GND
SDA	A4
SCL	A5
INT	Pin 2 (interrupt #0)

NOTE: This is a 3.3V device. If using the Arduino UNO or other 5V platform, be sure to power the MPU6050 breakout from the low voltage (3.3V) line. The SDA and SCL inputs will be fine, you do not need to worry about them.

THIS IS HORRIBLE SOLDERING (AND A BLURRY PHOTO)! YOU CAN DO BETTER!

This review is from: Kootek® Arduino GY-521 MPU-6050 Module 3 axial gyroscope accelerometer stance tilt module (Misc.)
I am fairly new to Arduino projects, so this was a perfect breakout board to get my feet wet. The major down side to this product is that its difficult to find info on it (as said by other users). After finding some code, the unit seems to work pretty well... I used this board on a quadcopter to help with the inherent stability issues.

Hopefully I'll save some people the time to dig up this information. Here is a link for those doing arduino projects:
[...] --> See first comment on this post

here's the source code for the I2C library I used:
[...] --> See first comment on this post

This library contains two helpful examples; one that allows the raw accelerometer and gyroscope values to be accessed, and the other calculates Euler angles, yaw pitch roll, world accelerations, and quaternions. If you using this with an arduino, make sure that the I2C library and a MPU6050 library are in the Arduino sketch folder, this will allow it to compile correctly.

This was also difficult to find:

The GY-521 breakout board is wired to the Arduino Mega as followed:
Vcc - 3.3V
GND - GND
SCL - SCL (pin 21)
SDA - SDA (pin 20)
ADO - GND
INT - D2

The GY-521 breakout board is wired to the Arduino Uno as followed:
Vcc - 3.3V
GND - GND
SCL - D5
SDA - D4
ADO - GND
INT - D2

Hi. I am trying to read the raw data with a Arduino Duemilanove. Would you please tell me how can I wire the GY-521 to the Arduino board. Thank you.

Probably trying to be helpful... but some bad info.... Cost me a good bit of time!!! as I started here!!
Can you EDIT your post please cheeky?
UNO
SCL - A5 (NOT D5)
SDA - A4 (NOT D4)
These are plainly important!
Vcc - Maybe 3.3 works? board seems designed for 5V in with a regulator onboard for sensor??? Mine works on 5V

The Arduino Leonardo/yun has different I2C pin locations as well.

D2=SDA (not A2!)
D3=SCL (not A3!)

And they are also broken out in the same order in the very last two headers by the rest button and mounting hole. I don't own a Leonardo but I believe the silk screen is labeled. You may also have to change any calls as xxx.receive() to xxx.read() for arduino IDE versions 1.0 and higher I believe.

I love arduino but hate trying to recall all the pin functions, seems they constantly move them around.

For those asking, I2C bus usually only needs 4 wires between the device and arduino - ground, voltage, SCL and SDA. Just find the location of SCL/SDA for your specific board.

Did you ground the AD0 pin?
Was INT Connected to D2?
Did you put a 10KOhm Pull-up for the SCL and SDA?
As I'm still getting connection Failed.
