SpeedyBee F405 AIO 40A Flight Controller

The SpeedyBee F405 AIO is engineered to solve the common headaches of micro and cinewhoop builds. Its standout feature is the dual-sided CNC heatsink, which not only protects the sensitive MOSFETs and flight controller chips from impact but also allows the 40A ESC to handle high-current bursts without overheating.

Maintenance is effortless thanks to Wireless Tuning 2.0. You can adjust your PIDs, change motor directions, and even flash firmware wirelessly using your smartphone. For frames where the USB port is buried behind ducts or carbon, SpeedyBee includes a USB-C Extension Board, allowing you to mount a secondary port in a much more accessible location.

Key Performance Highlights:

• Wireless Everything: Use the SpeedyBee App (Bluetooth) to configure Betaflight or INAV and flash firmware at the field—no laptop needed.

• 32-Bit Performance with Bluejay: Pre-flashed with Bluejay JH-40 (48kHz) firmware, providing smoother throttle response and better efficiency than standard BLHeli_S boards.

• Heavy-Duty Cooling: Integrated aluminum heatsinks significantly improve thermal dissipation, making this one of the most reliable AIOs for 4S and 6S power.

• Built-in Barometer: Features the high-precision SPA06-003 barometer, essential for stable altitude hold in Cinewhoops and GPS rescue missions.

• DJI O3 Plug-and-Play: Includes a dedicated 6-pin port for the DJI O3, RunCam Link, or Caddx Vista, ensuring a solder-free digital HD setup.

• Rich Accessory Suite: Comes with a soldering practice board, external BEC (switchable 5V/9V), and a power expansion board for LEDs.
