SpeedyBee F405 V5 + 55A OX32 Deluxe

SpeedyBee F405 V5 OX32 55A Stack is a combination of flight controller and ESC with a mounting hole spacing of 30.5×30.5mm. The board supports Betaflight and ArduPilot firmware, making it suitable for 5″ freestyle drones and 7″ long-range drones powered by 3–6S batteries. The flight controller features an integrated Bluetooth module for wireless configuration.

The Deluxe stack also includes a SpeedyBee Smart Power Tester (smoke stopper), soldering practice board, buzzer, external USB-C connector, and a power expansion board. The SpeedyBee Smart Power Tester interrupts the power supply in case of a short circuit (or high current draw), thus protecting the electronics. It is primarily used during component testing or when first connecting the battery to a newly built drone.

The flight controller is based on the STM32F405 processor with ICM42688P gyro and SPL06-003 barometer for altitude measurement. It has 16MB of memory for blackbox, a 5V/2.5A BEC for powering the receiver, peripherals, and LED strips, and a 9V/2.5A BEC for the camera or video transmitter, with the 9V output supporting remote switching via PINIO. The 4.5V/1A output enables powering the receiver or GPS even when connected via USB without a battery. It includes an OSD chip AT7456E for analog video and a connector for direct connection of digital video transmission. The flight controller has 4 motor outputs and an additional 2 signal outputs for servos. The flight controller comes coated with a protective layer against moisture.

The stack is complemented by a 4-in-1 ESC capable of handling up to 55A. For better current transmission, the ESC utilizes nickel bus bars. It is equipped with an aluminum heatsink that helps dissipate heat and protects electronics from debris. The ESC includes a current sensor and a TVS diode for surge protection. The ESC uses OX32 firmware, which is an alternative to BLHeli_32. Configuration is done using the OX32 configurator.
