Note: Please upgrade the compatible R9M / R9M Lite module with the latest firmware simultaneously, and rebind the devices after the update.

The FrSky 900MHz 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.

 

Features

  •  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
