The IMU that I am using at the moment is the 9DOF from www.drotek.fr . It’s compact and it has onboard gyroscope, acceletometer and magnetometer. Unfortunatly there is not a native configuration for this board into the multiwii software, so here is the correct define:

#define ACC_ORIENTATION(X, Y, Z) {accADC[ROLL] = -X; accADC[PITCH] = -Y; accADC[YAW] = Z;} #define GYRO_ORIENTATION(X, Y, Z) {gyroADC[ROLL] = Y; gyroADC[PITCH] = -X; gyroADC[YAW] = -Z;} #define MAG_ORIENTATION(X, Y, Z) {magADC[ROLL] = Y; magADC[PITCH] = -X; magADC[YAW] = -Z;}
