OVERVIEW
The FrSky 900MHz R9 MM-FC (OMNIBUS F4 Nano V7) uses the ICM20608 over SPI to produce stable flight performance. Integrated with the R9 MM-FC receiver mounted onboard, and the ICM runs the 32k Gyro loop perfectly. Also onboard is an AB7456 OSD chip for the Betaflight OSD.
An on-board R9 MM-FC receiver and 20mm x 20mm mounting holes make it perfect for a super clean micro quadcopter build. It supports 3-6S LiPo direct input and has 6 hardware UARTs and an I2C port.
FEATURES
- Tantalum Capacitors added for noiseless gyro reading
- Solder pads added for SmartAudio and Camera Control (next to Video pads)
- FPC port for FrSky FC receivers like the R9MM-FC / RXSR-FC receiver
- PWM pads on corners
- Upgraded BEC, 3A output
