SpeedyBee F405 AIO V2 40A 8Bit 3-6S Flight Controller with CNC Heatsink

The SpeedyBee F405 AIO V2 puts an F405 flight controller and a 40A 8-bit 4-in-1 ESC on a single 25.5 x 25.5mm board, and this version adds a CNC-machined aluminium heat-dissipation structure over the ESC. It suits compact freestyle, racing and cinewhoop builds on 3–6S where one board saves weight and wiring.

Key features

• STM32F405 with ICM-42688P gyro and 8MB blackbox flash
• Integrated 40A 8-bit ESC running Bluejay (JH-40, 48kHz) with bidirectional DShot for RPM filtering
• CNC aluminium heatsink helps keep ESC temperatures down on long, high-throttle flights
• Built-in Bluetooth for wireless configuration and firmware updates from the SpeedyBee app
• 9V BEC with a programmable VTX power switch, plus DJI Air Unit OSD support
• WS2812 LED control and multiple UARTs for receiver and GPS
