FlyingRC F4WSE F405 Pro

FlyingRC F4WSE Pro is a flight controller designed for airplanes and flying wings powered by 2-6S LiPo batteries. The set consists of a flight controller, an expansion board for power and signal distribution, external USB-C modules and a microSD card slot. The board supports ArduPilot, INAV and Betaflight firmware, and ArduPlane is preloaded from the factory. The pin layout corresponds to the Matek F405-TE board, which means that in most builds the established wiring scheme and firmware can be used.

The flight controller is based on the STM32F405RGT6 processor at 168MHz in combination with the BMI270 gyroscope and the SPA06-001 barometer for altitude measurement. The board does not have a built-in compass, so an external module is required for navigation modes. For analog video transmission, the board has an OSD chip displaying telemetry data directly in the video and two switchable camera inputs, between which you can switch in flight via a transmitter channel. Blackbox logs are stored on an external microSD card module with support for cards up to 32GB — the module is connected by cable and can be placed outside the unit.

For connecting peripherals, there are 6 UARTs, 12 PWM outputs for servos and motors, and one I2C bus. Six PWM channels are brought out to pin headers, two to solder pads and four to a connector. The SBUS inverter is integrated on the board and internally connected to the RX pin of UART2. The receiver, GPS module, digital video transmitter and ESC are connected via SH1.0 connectors without soldering, while the remaining pins are available on the pin headers and solder pads of the expansion board. An addressable WS2812 LED strip can be connected to pad S12.

The power section offers two BEC rails — 5V/5A for servos and 5V/3A for other electronics, i.e. the receiver, GPS and video transmitter. For a board of this size, this is above-average load capacity and eliminates the need for an external converter on smaller aircraft. The onboard current sensor measures up to 80A continuously. An external airspeed sensor can be connected via I2C (supported types are MS4525 and DLVLR-L10D), which improves airspeed calculation on fixed-wing aircraft; it is not included in the package.

The flight controller is connected to the expansion board with the included M2 standoffs, and to the ESC with a single 8-pin SH1.0 cable, which carries the signal for both motors and battery voltage measurement.
