In recent years, the FPV drone market has seen a rise in compact, integrated flight controller solutions tailored for small but powerful builds. One such product drawing attention from both hobbyists and professional pilots alike is the Speedybee F405 AIO.
This all-in-one board combines the functions of a flight controller and ESC into a single unit. But what exactly does it offer? Is it a good fit for freestyle, racing, or cinematic drones? In this article, we’ll break down its features, evaluate where it stands in the FPV ecosystem, and highlight situations where it might (or might not) be the right tool for the job.
- What Is the Speedybee F405 AIO?
The Speedybee F405 AIO is a 3–6S-compatible flight controller with a built-in 40A ESC. It belongs to the newer generation of AIO (All-in-One) boards that aim to simplify drone builds by reducing the number of components, cables, and potential points of failure.
Key specs include:
- MCU: STM32F405 chip
- ESC: 4-in-1 40A (Bluejay firmware pre-flashed)
- Mounting: 25.5×25.5mm M2
- Connectivity: Wi-Fi and Bluetooth via Speedybee App
- Supported Protocols: DShot300/600, RPM filtering via Bluejay
- Integrated 16MB Blackbox storage
The goal of this AIO is not only to save space and weight but also to provide on-the-go tuning and configuration via a mobile app—something that has become a hallmark of Speedybee’s recent product line.
- Key Features of the Speedybee F405 AIO
2.1 Compact but Capable Design
With its 25.5×25.5mm mounting size, the Speedybee F405 AIO is ideal for 3-inch to lightweight 5-inch builds. It’s especially popular among cinewhoop and toothpick-style drones where space is limited.
Despite its small size, the board is equipped with a 40A ESC, which offers ample headroom for motors pulling higher current under load. This makes it suitable for medium-power builds on both 4S and 6S setups.
2.2 Wireless Configuration Options
Like many of Speedybee’s flight controllers, this AIO board comes with Bluetooth and Wi-Fi functionality. Users can connect to the Speedybee app for:
- Betaflight configuration
- Firmware flashing
- Blackbox log access
- ESC firmware upgrades (via passthrough)
This wireless approach is especially useful for field tuning and makes the board appealing to pilots who prefer not to carry a laptop.
2.3 Bluejay Firmware and RPM Filtering
Pre-flashed with Bluejay ESC firmware, the F405 AIO supports RPM filtering, a popular feature for reducing noise and improving flight performance. It’s a welcome inclusion for pilots who want to achieve smooth flight characteristics without flashing custom firmware themselves.

- Performance and Reliability: What to Expect
The Speedybee F405 AIO delivers stable performance under moderate to aggressive use. Its current rating (40A continuous per motor) is more than sufficient for most 3″ to 4″ props and even some lighter 5″ freestyle setups using efficient motors.
Thermal performance appears balanced under typical load scenarios. However, for high-throttle builds flying in hot climates or enclosed ducts (such as cinewhoops), some airflow or thermal planning is advisable.
From a firmware standpoint, the STM32F405 MCU is widely supported in the Betaflight community, and many custom settings or features (e.g., OSD, RPM filtering, GPS integration) are accessible.
- Use Cases: When to Choose the Speedybee F405 AIO
This AIO board is suitable for a range of flying styles and configurations:
- Cinewhoops: Great for indoor or tight-space flying where mounting space is limited and reliability is crucial.
- Toothpicks and Sub-250g Builds: Lightweight boards like this are a natural fit.
- Freestyle (Lightweight 5-inch): Capable of powering efficient 5” motors on 4S without overheating.
- Portable Field Setups: Thanks to wireless tuning, this board is convenient for those flying in locations without easy access to computers.
- Considerations Before Buying
Despite its strengths, there are a few points pilots might want to evaluate:
- No USB Port: Some users prefer having a backup USB port in case wireless fails. The F405 AIO relies mainly on wireless configuration.
- Limited UARTs: AIO boards often have fewer UARTs compared to full-sized stacks. This can be restrictive if you plan to add GPS, HD digital systems, barometers, and other peripherals.
- Repair Complexity: Since ESC and FC are integrated, if one side fails, the whole board may need replacing.
That said, these trade-offs are typical of most AIO boards and not specific to this model.
