Description

The SpeedyBee F745 AIO board consolidates flight control and power delivery into a single, high-density unit designed for performance-oriented micro and nano drones. Its STM32F745 microcontroller provides ample processing headroom for complex Betaflight filters and rates, while the MPU6000 IMU ensures stable gyroscopic data. The integrated 35A BLHeli_S ESCs support DSHOT protocols for responsive, jitter-free motor control across a wide voltage range.

Electrical design incorporates robust power filtering, highlighted by the included 35V 470uF capacitor, to minimize noise and ensure clean video transmission. The board’s layout provides dedicated UARTs for peripherals like GPS or telemetry radios, and includes direct support for DJI Digital FPV Air Units via a supplied cable. Its construction prioritizes a low-profile, vibration-damped installation using the included silicone grommets and O-rings.

Key Features

  • High-performance STM32F745 MCU with 8MB onboard flash for extensive Blackbox logging.
  • Four independent 35A BLHeli_S ESCs capable of handling high-current bursts for aggressive maneuvers.
  • Integrated BMP280 barometer for altitude hold functionality in compatible flight firmware.
  • Onboard Bluetooth module enables wireless tuning and configuration without physical USB connection.
  • Comprehensive I/O breakout with four full UARTs, dedicated buzzer pads, and current sensor input.
  • Type-C USB port provides reliable connectivity for firmware updates and direct parameter adjustment.
  • Compact 25.5x25.5mm form factor with anti-vibration mounting system for noise-isolated installations.
  • Direct plug-and-play cable support for DJI Digital HD FPV systems simplifies wiring.

Applications

  • High-performance 3-inch and 4-inch FPV freestyle and racing quadcopters requiring a compact AIO solution.
  • Micro long-range builds where integrated ESCs and flight control reduce wiring complexity and weight.
  • Betaflight-based cinewhoop platforms needing reliable OSD and barometer for stabilized flight modes.
  • DIY drone projects utilizing DJI Digital HD FPV systems, leveraging the included Air Unit cable.
  • Experimental and lightweight UAV platforms where the 25.5x25.5mm mounting pattern is standard.

Frequently Asked Questions

What is the maximum input voltage for the SpeedyBee F745 AIO's ESCs?

While the official spec sheet should be consulted for absolute limits, AIO boards with 35A BLHeli_S ESCs like this are typically designed for 2-6S LiPo battery input (approximately 8.4V to 25.2V). The included 35V capacitor indicates a design tolerance for spikes within this range. Always verify against the manufacturer's latest documentation before connecting high-voltage packs.

Does this AIO flight controller support ExpressLRS receiver wiring?

Yes, the SpeedyBee F745 AIO provides multiple UARTs (UART1 through UART4) for serial receivers. An ExpressLRS receiver can be connected to any of these UART's RX and TX pads, configured in Betaflight's Ports tab, and set to CRSF protocol in the Configuration tab. Ensure you provide 5V power to the receiver from a dedicated 5V pad or via a compatible servo connector.

How do I activate and use the onboard Bluetooth feature?

The onboard Bluetooth is powered when the flight controller is connected to a battery. You can pair your mobile device with the controller via the SpeedyBee app. Once paired, the app allows wireless adjustment of Betaflight PID tunes, rates, and other parameters without a USB cable, provided the FC remains powered. The Bluetooth chip is a 2.4 GHz combo module also used for Wi-Fi flashing.

What is the purpose of the included external USB port module?

The external USB port module provides an alternative, more accessible Type-C connection point. It is particularly useful in tight builds where the onboard USB port is obstructed by frame components or a camera. The short 5mm cable allows you to route the port to a more convenient location on your drone for easier firmware updates and wired configuration.
