Newbie need help ...
I have to connect a 10 DOF sensor to an Arduino uno
This board combines
· L3G4200D three-axis digital gyroscope
 · ADXL345 triaxial accelerometer
 · BMP085 pressure sensor
 · HMC5883L triple axis magnetometer
To find under Multiwii sketches under : #define PIPO// 9DOF board from erazz
I have find the pin for 5v, 3,3v and GND

I connect pin A4 to "SCL" and A5 to "SDA" correct ?
Witch pins on arduino for "INTG" "DRG" "INTM" on sensor ?
Thanks for help! Sorry for my poor English!
Merci d'avance

They are not used.
Leave unconnected.

Thanks for help,
The other connection are right !?
5v AND 3,3v or only 3,3v

One of them is enough...

Hello, I wonder if a4 and a5 should not be reversed (scl on a5 and sda on a4)...
Did you tried ? (No risks)
