Product overview
The BrotherHobby Returner 3-8S F722 Betaflight Flight controller is a flight-control board for UAV integration. Its hardware combines an STM32F722RET6 processor with two ICM-42688 IMUs, an SPL06-001 barometer, AT7456E OSD hardware and a 256M black box. The board measures 37.25 × 37.25 mm and weighs 8.6 g, with a 30.5 × 30.5 mm mounting pattern and 4 mm mounting holes. Electrical specifications include 3S-8S input power, 5V/2A and 12V/2A BEC ratings, and ESC outputs M1-M8.
Peripheral integration includes plug-in and soldered connections for DJI, receivers, the GPS magnetometer interface and the camera interface. Adjustable LEDs also support both connection methods, while VTX connection support is specified for soldering. Receiver protocols comprise SBUS, IBUS, DSM2/X, TBS and CRSF. The controller lists UART1 through UART6, with UART5 identified for ESC telemetry, alongside IIC, RSSI, buzzer support and a CUR pad. Other features include Type-C USB, a DFU button and a debugging interface. Its target firmware is betaflight_4.5.1_STM32F7X2_BROTHERHOBBYF722.
