Arduino DUE + MPU 6050 Dont work at all

Other Hardware Sensors
1

Hello
I have an Arduiono Due and i want connect it to my MPU6050 Breakout Board from drotek.fr

Well i cant get any signal from the sensor board even the IC2 Scanner fail to detect it:

Do i need to solder or to ad a resistor add teh back of the brake out board at the pins ?

Did i connect it right ?

Pin1: at 3,3V
Pin2: at GND
PIN3: connected 3,3V
Pin4: at SDA (PIN20)
PIN5:at SCL(PIN21)
Pin6: not connected

thanks for help

If you got this one: http://www.drotek.fr/shop/en/home/42-mpu6050-gyro-accelerometer.html, pin 1 has to go to 5V and pin 3 is not connected.

Post the sketch you're testing with.

IT should work also with 3,3V at Pin PIN1 ? with Arduiono Due So far i know the MPU6050 its 3,3V compatible ?
Howt is about this pull up option ?

The MPU-6050 (the sensor chip itself) will work at 2.375V.
If you supply 3.3V to pin 1 of the breakout board, the voltage regulator on the breakout board will create a voltage that is a little lower. Perhaps 3.2V. That is no problem for the MPU-6050, so it is fully 3.3V compatible.

The 3.3V pin of that breakout board is the output of the voltage regulator, leave it open.

There was a problem with the Wire library of the Due. It had to do with the return value of Wire.endTransmission(), making the i2c_not to work on the Due.
I don't know what the status is of that error at the moment.

Hello thanks for support,

I tested it with my olderArduino Uno Board with I2C Scanner and the MPU 6050 Sketch and it was working well...

Seems the Arduino Due Libarys still have some Bugs... :~

Now i have to implement the whole stuff on my PIC32 so big job occurs ahead :disappointed_relieved:
