This is a replacement Gyro Box board for your omnibus flight controller. We sell both the MPU6000 and ICM20608 versions depending on what flight controller you are using. The IMU is often something that breaks in a bad crash, but this box allows you to easily replace it without the need for an entire FC replacement.
These gyro boxes will work with the Omnibus F4 series of boards including the fireworks. It does not work on the Omnibus F7 V2.
