The SpeedyBee F405 AIO V2 is a high-performance all-in-one controller specially designed for FPV racing drones. It is compatiblewith mainstream chassis through standard 25.5×25.5mm mounting holes and offers two versions of 35A/40A power supply options. It is compatible with a wide voltage range of 3-6S to meet various flight requirements. It is an ideal choice for beginners to assemble and for experienced players to modify. The core configuration maximizes performance: it is equipped with the STM32F405 main control chip and the ICM-42688P gyroscope. The independent power supply design is combined with large-capacity filter, ensuring precise and stable flight response. It integrates Bluetooth tuning function, allowing for wireless parameter configuration through the mobile APP without the need to connect to a computer, unlocking the convenience of firmware upgrade. It includes a 9V BEC power supply and programmable switches, supporting transmission signal on/off control, effectively preventing overheating of the equipment, and is compatible with devices such as DJI Sky Station for direct insertion use. The design takes into account both practicality and durability: the solder pads have been fully optimized and centrally arranged, combined with anti-corrosion paint
protection, making it easier to install even in dusty environments. The 40A version is equipped with a CNC metal heat dissipation jacket, while the 35A bare board version is lightweight (only 8.9g), suitable for small chassis installation needs. It supports WS2812 strobe light strips control, OSD display, and other expansion functions. It has 4 groups of full-function serial ports to meet external device connections. Whether it is a 2-4 inch ring drone or a lightweight 5-inch flower-shaped aircraft model, it can provide stable and reliable power and control support.
