SpeedyBee F405 WING Flight Controller (Fixed Wing)

SpeedyBee F405 WING — a compact and functional flight controller designed specifically for fixed-wing aircraft and VTOLs. The device consists of three separate boards: a power distribution board (PDB), a main flight control board, and a wireless communication board. The package includes various cables, connectors, mounting hardware, and a detailed manual with useful wiring diagrams, ensuring quick and reliable integration into your wing.

The controller is based on the STM32F405 microcontroller with a clock frequency of 168 MHz and 1 MB of flash memory, compatible with both iNav and ArduPilot, making it a versatile solution for various aircraft models. For controlling motors and servos, the controller has up to 11 PWM outputs, as well as additional functions for connecting peripherals via 6 UART ports.

Key Features

• Support for wireless programming via the SpeedyBee app, allowing settings and firmware to be changed from a phone or computer in the field.
• Compatibility with various types of flying wings, including VTOLs.
• Wide input voltage range: 7-36V (2-6S LiPo).
• Up to 11 PWM outputs for motors and servos (12 PWM pads are available on the device: 11 + 1 «LED» pad).
• 6 UART ports for connecting GPS, telemetry, and other accessories.
• Built-in battery voltage indicator with LEDs and four separate LED ports with their own driver.
• Ability to connect Wi-Fi and Bluetooth for wireless access.
