Wiring Diagrams and Connections

The manual includes several diagrams illustrating the connections for various components:

Main Connections (Flight Controller & ESC)

A diagram shows the SPAN-F7-BT-HD Flight Controller and the BL32 50A 4in1 ESC. Key connections include:

• ESC to Flight Controller: Motor signals (M1-M4), Current sensor (CUR), UART (TX/RX), Power (BAT/GND).
• Power Input: 3-6S LiPo battery connects to the ESC's BAT and GND terminals.
• Motor Outputs: Motors 1 through 4 connect to the corresponding pads on the ESC.
• Bluetooth: Connections for Bluetooth functionality are indicated.

VTX Connection

Diagrams show connections for TBS VTX (Tramp HV, SmartAudio) and other VTX types. Connections typically involve:

• Power: +5V, +9V, GND
• Video Signal: Vin, Vout
• Control Signal: TX/RX for SmartAudio or Tramp control.

LED & Buzzer Connection

Connections for LED and Buzzer are shown, typically using dedicated pads on the flight controller (+5V, GND, BZ-, LED).

Camera Connection

A diagram illustrates connecting a camera (e.g., RunCam Micro Swift 3) to the flight controller, usually via dedicated Camera pads (e.g., VIN, GND, CAM).

GPS & Compass Connection

Connections for a GPS module are shown, including:

• Power: +5V, GND
• Data: TX, RX (for GPS data)
• Compass: SDA, SCL (for compass data)

Note: The manual advises that the compass function may not be fully supported on Betaflight firmware and recommends INAV firmware for complete compass functionality.

Bluetooth Connection

Instructions are provided for connecting to the Speedy Bee APP via Bluetooth:

1. Enable the configuration/MSP feature of UART5 and set the baud rate to 19200.
2. Enter CLI commands: set pinio_config = 129,1,1,1 and set pinio_box = 0,255,255,255.
3. Resource configuration: resource PINIO 1 C13
4. Save the configuration.
5. Power the Flight Controller.
6. Open the Speedy Bee APP and search for Bluetooth devices.
7. Select the GEPRC icon to connect.

Configuration Notes

The manual emphasizes the importance of correct serial port configuration within the flight controller firmware (e.g., Betaflight Configurator). Key points include:

• Serial Ports: Various UARTs can be configured for different peripherals like receivers, VTX control, GPS, etc.
• Receiver Configuration: Users can select between DJI HDL or SBUS protocols. For serial receivers (e.g., Spektrum, SBUS, IBUS), a serial port must be configured in the Ports tab, and the correct Serial Receiver Provider selected.
• MSP: It is advised not to disable MSP on the first serial port (USB VCP) unless the user is certain, as it may require reflashing the firmware.
• CLI Commands: Specific CLI commands are provided for certain configurations, such as Bluetooth setup and receiver protocols (e.g., set serialrx_halfduplex = ON, set serialrx_inverted = ON).
