Product overview
The BrotherHobby Returner 3-8S F435 V2 is a Betaflight flight controller for integration into a UAV build. Its electronics combine an AT32F435RGT7 processor, ICM-42688 IMU, SPL06-001 barometer and AT7456ELAH OSD, with a 16M black box. The board measures 38.5 × 38.5 mm and uses a 30.5 × 30.5 mm mounting pattern with 4 mm holes, defining its installation footprint. Weight is 7.8g. Power input spans 3S-8S, while the BEC outputs are rated at 5V/2A and 12V/2A.
Integration connections include M1-M8 ESC outputs, C1 and C2 camera interfaces, a CUR current sensing pad and a Type-C USB port. Six serial ports run from UART1 through UART6, with UART1 designated for ESC telemetry. Receiver support covers SBUS, IBUS, DSM2/X, TBS and CRSF; DJI, IIC, external adjustable LEDs and a buzzer are also supported. The specified firmware target is betaflight_4.5.0_AT32F435G_BROTHERHOBBYF435.hex. This is a flight controller component for a larger assembly, with the listed peripheral support describing integration capabilities.
