FrSky R9|RXSR Pilot Flight Control

The FrSky Pilot series flight controller is an All-in-One module that supports comprehensive flight control functions with pre-installed powerful INAV (The support of other open-source software like Ardupilot and Betaflight are ongoing.) and F.Port 2.0 software. This control system is targeted towards RC hobby enthusiasts who are looking for a complete system combining power management, a powerful graphic FrSky OSD, and plenty of IOs.

The R9/RXSR Pilot is comprised of a three-layer stack:

1.A mainboard providing power for servos and for a video system with switchable voltages, current measurement and general connectivity (6 full UARTs, I²C, 12 servo/motor outputs, 2 analog inputs, video input/output)

2.A processing board using a powerful STM32F765 at its core, boasting 1MB of flash memory, and 512KB of RAM capable of running the INAV, Ardupilot and Betaflight flight control software. It integrates an ICM20602 IMU, FrSky’s latest

, and an SPL06 high precision barometer. An SPI bus connector allows for optional connection of a second vibration isolated IMU, which can be mounted to the board, or other peripherals. An SD card slot allows for data storage including BlackBox logging. It also includes a piezo audio transducer for system notifications and lost model locating.

Any FrSky receivers with a standard FPC interface can be connected directly to the processing board (RXSR-FC / R9MM-FC-OTA). All F.Port 2.0 Capable Receivers (Archer and Tandem Series Receivers, etc.), SBUS receivers, and some others with serial ports are also compatible.
