FrSky Pilot FC with R9MM or RXSR

The FrSky Pilot flight controller is an All-in-One module that supports comprehensive flight control functions with pre-installed powerful INAV (support of other open-source software like Ardupilot and Betaflight is in progress) and F.Port 2.0 software. This flight 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. This FC is mainly targeted for fixed wing aircrafts, but can be used for any multirotors with up to 12 motors!

FrSky Pilot FC has three-layer stack design. The bottom board provides power for servos and for a video system with switchable voltages, current measurement and general connectivity.

The second layer has powerful STM32F765 MCU with boasting 1MB of flash memory, and 512KB of RAM capable of running the INAV, Ardupilot and Betaflight flight control software. It has integrated an ICM20602 IMU, FrSky’s graphic OSD, and an SPL06 high precision barometer. An SD card slot allows for data storage including BlackBox logging. It also includes a piezo audio transducer (buzzer) for system notifications and lost model locating.

FrSky Pilot has two flat flexible cable interfaces on the top of the FC. One is for the RXSR-FC or R9MM-FC receiver module, another for the external Gyro module with ICM20601/ICM20602/MPU6000 IMU.

You can connect up to 12 servo outputs to this flight controller, 6 UART ports, 2 analog inputs, video in/out and even I²C interface.
