The FrSky 900MHz R9 MM-FC (OMNIBUS F4 Fire works V2) uses the ICM20608 over SPI to produce stable flight performance. Integrated with the R9 MM receiver mounted on-board protection box, and the ICM20608 runs perfectly under 32k Gyro loop. Also onboard are a barometer and AB7456 OSD chip for the Betaflight integrated OSD.

The R9 MM-FC (OMNIBUS F4 Fire works V2) supports 3-6s Lipo direct input, built-in hall Current Sensor and Power Filter as well. The on Board PDB is tweaked by using 12-Layer PCB design. There is only 0.2-0.5 mohm internal resistance from input to each output pad.
