The FrSky R9 MM-FC (OMNINXT F7) has been developed based on the newly designed NXT architecture. It has an integrated R9 MM receiver mounted in a protective box. For orientation this flight controller uses the venerable MPU6000 Gyro up to 8kHz but also has an ICM20608 mounted in a padded/protective case. The damped protective case allows the ICM20608 to run perfectly with a 32k loop time. The NXT also comes with 2 different BECs and 6 UARTs.
The R9 MM -FC (OMNINXT F7) supports 3-6s Lipo direct input, a built-in BEC for camera / VTX and a Power Filter. This FC is designed to be paired with 4in1 ESCs through a SH1.0 8P socket but also retains signal pads for connection of individual ESCs.
