Missing compass/magnetometer for yaw

[jumpjack]

MPU6050 (and gyros+accelerometers in general) is not reliable for yaw, but I can't find any magnetometer/compass in the list of available components.
Yaw from an accelerometer is not reliable because there is no horizontal gravity/acceleration, only noise, hence yaw is calculated, not actually detected.

We need a 6-axis (accel+magnet) or 9-axis (accel+magnet+gyro) device to know yaw.

Examples:

• GY-511 (compass+ accel)
• GY-652 (compass only)
• GY-89 (compass+gyro+accel)
