The SpeedyBee F7 V3 is a high-performance flight controller for FPV racing, freestyle and long-range drones. The page says it uses an STM32F7 processor and supports wireless configuration over Bluetooth and Wi-Fi, with an integrated Betaflight OSD.
The specification list gives an STM32F722 MCU, a BMI270 gyro, a BMP280 barometer, an AT7456E OSD chip, a Type-C USB port, 3S-6S LiPo input, dimensions of 41 x 38 x 8.1 mm and a weight of 10.7 g. The page showed 6 units remaining.
STM32F722 processor: for fast signal processing.
BMI270 gyro and BMP280 barometer: as listed.
Betaflight OSD: with an AT7456E chip.
Bluetooth and Wi-Fi: a 2.4 GHz combo chip for wireless setup.
Type-C USB: as listed.
30.5 x 30.5 mm mounting: with 4 mm holes.
A flight controller is the brain of a multirotor or fixed-wing aircraft. It reads the gyroscope, and where fitted the accelerometer, barometer and compass, and runs a control loop that compares what the aircraft is doing with what the pilot asks for. It then sends new speed commands to the motors through the ESCs or servos many times each second. A faster processor and a better gyro allow a higher loop rate and a more locked-in feel.
Wiring and firmware decide what the board can do. The number of UARTs limits how many receivers, GPS units, telemetry radios and video systems you can connect, the PWM or motor outputs limit how many motors and servos it can drive, and the input voltage range must suit your battery and power module. Before you buy, check that the firmware you want to run supports the board and that its mounting pattern fits your frame.
Set up carefully. Flash a firmware that is listed as supported, configure the receiver protocol, set the motor order and direction, calibrate the accelerometer and, for larger aircraft, the compass, and always test with the propellers removed first. Keep the board isolated from vibration with soft mounts where the design calls for them, and never power it with a supply that is outside the rated input voltage.
Keep the aircraft safe. Confirm your failsafe settings and arming switch before the first flight, keep a backup of your configuration, and update firmware only when you have a reason to. A flight controller is a safety-critical part, so use the wiring diagram from the maker and avoid guesswork with power connections.
