Dual MCU or Dual IMU?

Butterflight developers have created the 
spring IMU-F board that has two MCUs. The second one is dedicated to filtering the IMU (gyro) readings using some fancy maths to allow the main MCU to focus on running flight control stuff. This ensures that the main MCU gets accurate and clean sensor data.

On the other hand, Airbot have released the 
OmniNXT F7 that uses a dual IMU approach that lets you get the best of the robust MPU6000 (8Khz updates) whilst also getting the benefits of the 32Khz updates from the ICM20608. To handle all this data they slapped on a STM F7 MCU.

So depending on which side you choose we have you covered. If you can’t decide, why not buy both??
