The SpeedyBee F405 AIO V2 is a high-performance all-in-one controller specially designed for FPV racing drones. It is compatible with 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 a large-capacity filter, ensuring a precise and stable flight response. It integrates Bluetooth tuning, allowing wireless parameter configuration via the mobile APP without connecting to a computer, unlocking the convenience of firmware upgrades. It includes a 9V BEC power supply and programmable switches that support transmission signal on/off control, effectively preventing equipment overheating, and is compatible with devices such as the 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) and suitable for small-chassis installations. 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.
