SpeedyBee F405 WING MINI Fixed Wing Flight Controller

The SpeedyBee F405 WING MINI Fixed Wing Flight Controller is a full-featured, compact avionic suite engineered by SpeedyBee specifically for intermediate and sub-250g fixed-wing aircraft, gliders, and compact vertical takeoff and landing (VTOL) platforms. Despite its incredibly small footprint, this mini-sized board packs the computational performance of a full-scale ground control processing hub. Driven by a powerful STM32F405 microcontroller running at 168MHz, it integrates an advanced ICM-42688-P inertial measurement unit (IMU) alongside a precision SPL006-001 barometer. This pairing allows pilots to load comprehensive navigation suites like INAV or ArduPilot directly into a tight glider cockpit layout without modifying structural airframe components.

Plug-and-Play Architecture with Integrated Smart Wireless Tuning 2.0

Routing messy wire looms inside narrow carbon fiber or EPO foam fuselages can complicate field assembly and introduce signal noise. The SpeedyBee F405 WING MINI addresses this by incorporating a clean, modular layout highlighted by dedicated plug-and-play pin-socket channels for GPS modules, telemetry links, digital or analog FPV video transmitters, and receivers. On its reverse side, neatly labeled solder pads provide advanced builders with a highly secure platform for deep configuration changes. Furthermore, the board introduces Wireless Tuning 2.0, an upgraded onboard BLE Bluetooth and Wi-Fi system. This interface lets pilots flash firmware, tweak PID controller configurations, change motor directions, and analyze MicroSD Blackbox logs instantly on their smartphone via the SpeedyBee App, completely bypassing the need for a laptop or OTG cables on the flight line.

• Onboard MicroSD blackbox storage slot captures high-frequency system logging metrics.

Dual Analog Camera Merging and Power Subsystems

Capturing unique formation flight footage or executing long-range structural reconnaissance typically requires heavy, automated external gimbal systems. To solve this efficiently, the F405 WING MINI features built-in dual analog video switching hardware. By assigning a single channel on an RC transmitter to an INAV mode switch or ArduPilot relay command, pilots can switch the active downstream FPV video feed instantly between an analog nose camera (C1) and a downward or rear-facing tail camera (C2) mid-flight. Powering these complex components is a dedicated multi-channel Power Distribution Board (PDB) stack layer, featuring a 5.2V peripheral BEC (2A), a high-power adjustable 5V/6V servo BEC delivering 4 Amps of continuous current, and direct battery monitoring circuitry supporting 2S up to 6S LiPo power cells.

Technical Versatility and Open-Source Integration

Investing in the SpeedyBee fixed-wing ecosystem guarantees type-certification readiness and high operational safety margins for custom aircraft projects. Weighing an incredibly light 14.3g for the entire multi-board configuration stack (comprising the FC, PDB, and Wireless Expansion module), this platform delivers deep compatibility with essential external sensors—including digital differential airspeeds, external compass magnetometers, and analog RSSI receivers over a dedicated I2C bus channel. Pre-configured natively with the robust INAV target out of the box, it offers standard support for advanced autonomous flight protocols such as automated return-to-home (RTH), waypoint mission planning, and cruise stability modes, ensuring absolute safety for your aircraft.
