FrSky RXSR-FC OMNIBUS F4 V6 Control Board

Total: 0.00



The FrSky RXSR-FC (OMNIBUS F4 V6) uses the MPU6000 over SPI to produce stable flight performance. Integrated with the RXSR receiver mounted on-board in a protection box. It also features a barometer and AB7456 OSD chip for the Betaflight integrated OSD.

The RXSR-FC (OMNIBUS F4 V6) supports 3-6s Lipo direct input, and has 5 hardware UARTs
