In the ever-evolving world of FPV drones, choosing the right flight controller can make or break your build. Whether you’re chasing cinematic shots, diving buildings, or racing gates, having a reliable, feature-rich, and compact board is essential. That’s where the Speedybee F405 AIO enters the scene—a compact powerhouse tailored for pilots who demand performance without compromise.
In this article, we’ll explore why the Speedybee F405 AIO is gaining traction among FPV enthusiasts and why it might be the perfect upgrade for your next drone project.
- What Is the Speedybee F405 AIO?
The Speedybee F405 AIO is an all-in-one flight controller designed for 3–6S FPV builds. “AIO” stands for “All-in-One,” which means that this single board combines both the flight controller (FC) and the electronic speed controller (ESC), simplifying wiring, saving space, and reducing weight—critical elements for tight builds like whoops and toothpicks, or minimalistic 5” setups.
Unlike traditional stacks that require multiple boards and messy soldering, the Speedybee F405 AIO provides a clean solution without sacrificing power or features.
- Where to Buy the SpeedyBee F405 V4 Stack
While the SpeedyBee brand is available from many retailers, it’s recommended to buy from a reputable distributor that ensures fast shipping and official warranty coverage. You can find the genuine SpeedyBee F405 V4 FC+ESC stack at MEPSKING, an official FPV parts distributor known for customer support and fair pricing.

- Key Features That Make It Stand Out
- F405 MCU Chip: Balanced Power and Efficiency
Built around the STM32F405 MCU, this board provides a sweet spot between processing power and energy efficiency. It handles high-loop flight firmware like Betaflight and INAV with ease, offering excellent responsiveness and stability in all conditions.
- 40A BLHeli_S ESCs with Bluejay Firmware
The integrated 4-in-1 ESCs are rated at 40A continuous (45A burst), enough to drive even power-hungry motors on 5” freestyle builds. Bluejay firmware offers RPM filtering and bidirectional DShot, unlocking smooth performance and better gyro syncing—perfect for cinematic or racing flight modes.
- 25.5×25.5 Mounting Holes
Designed for whoop and compact frames, the 25.5×25.5mm mounting layout ensures compatibility with most micro or ultralight airframes, while still offering high amp support usually seen only on larger stacks.
- Plug-and-Play Simplicity
The Speedybee F405 AIO supports direct plug-in for DJI Air Units, analog VTXs, and GPS modules. You’ll find a smart layout with clearly labeled pads, plug ports, and pre-configured UARTs for a seamless building experience.
- Wi-Fi + Bluetooth App Configuration
This is a huge game-changer. With built-in wireless support, you can configure your PID tuning, rates, CLI commands, and firmware updates directly from the Speedybee app—no more dragging around a laptop to the field.
- Why Pilots Are Choosing the Speedybee F405 AIO in 2025
- Simplified Builds
The AIO design minimizes solder points, reduces wiring complexity, and helps eliminate issues caused by loose connections. For pilots who value clean builds and easy troubleshooting, this is a dream come true.
- High Current Handling in a Micro Layout
Unlike many micro AIO boards that cap out at 20–30A, this one punches at 40A, making it suitable even for aggressive freestyle or long-range 5” drones.
- Open Firmware Support
Whether you fly Betaflight, EmuFlight, or INAV, the Speedybee F405 AIO is open to a wide range of firmware options. That flexibility allows you to tailor the flight experience exactly to your needs.
- Built for Innovation
With features like onboard barometer, OSD, blackbox support, and voltage sensors, this board enables next-level tuning and telemetry without needing external modules.
