    The FrSky 900MHz/868MHz  R9 MM-FC (OMNIBUS F4 Fireworks 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 Fireworks 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.




    • Tantalum Capacitors can be added to the board (not included)
    • Solder pads added for VTX and Camera Control (next to Video pads)
    • The orientation of IMU FPC optimized
    • Gyro ribbon cable redesigned to fit without extending outside the board
    • Added an 8v BEC and LC Filter for the camera and VTX power
    • This board now has 5 UART ports




    • STM32 F405 MCU, Runs Betaflight firmware (supported from v3.2)
    • FrSky R9 MM receiver in protection box
    • ICM20608 over SPI Bus in dampening box (optional MPU6000)
    • 30.5×30.5 mm mounting holes
    • Supports Lipo direct plug-in (3-6S)
    • Built-in sensor damper
    • Supports 5V 1A BEC output (Buck)
    • Supports 8V 1A BEC with LC filter output for the camera and VTX (Buck)
    • STM32 controls OSD chip over SPI in DMA mode (Betaflight OSD)
    • Built-in hall Current Sensor
    • Built-in Professional Level PDB
    • More caps to reduce power noise
