Hi - I just soldered this up to my mwc board and am getting no readings.
1.
IMU - - BOARD
3.3v --> 5v
GND --> GND
SDA --> SDA
SCL --> SCL
Is this correct?
2.
In config.h
#define I2C_SPEED 100000L
is this correct?
3.
In config.h
#define GY_86 // GY_86
Any other suggested avenues to troubleshoot?
Thanks!

10DOF IMU GY-86 - No data...
Re: 10DOF IMU GY-86 - No data...
The I2C sensors on the GY-86 are powered by a 3.3V regulator.
That means that the I2C bus (SDA and SCL) can only tolerate 3.3V signals.
(The GY-86 has it's own pull-up resistors that are tied to 3.3V)
What MWC board are you using?
You might have to disconnect (de-solder) the MWC I2C pull-up resistors (which are connected to 5V)
Note: GY-86 is the same as Freeimu V04
