Hello all,
I've assembled a quadcopter using Arduino Uno R3 , Gy-521 with Multiwii. I've used this schematic
Everything worked great with the solderless cables from Arduino, so I started soldering.
Everything soldered and the Gy-521 doesn't seem to work properly when I use the MultiwiiConf GUI. It doesn't move or anything. It goes crazy whenever I remove the VCC or SCL and then stops, which means it is not dead. The LED flashes brightly and it's connected to the Ground and 3.3v in the board.
Any other idea?
I could've simply used a FC, but I really wanted to complete this project with the Arduino UNO.

- I've bought 3 new ones, same result with all of them, its not the MPU board.
- Switched cables
- Switched between A4 and A5 and SCL and SDA on the Arduino
- Removed everything else and tested only with the Accel on
- The battery on / only USB
- 3.3v Pin and 5v Pin
- Changed between Gy-521 and NanoWii sensor
- I2C speed 10000 / 40000
- define internal I2c
- Calibrated Accel in the GUI
- Everything I can think of at this point really...
Any other idea?
