5G modems: 5G modems can also be used, but at the moment they are much more expensive than 4G.

Assembly Steps

  1. Frame and Core Setup:

    • Assemble the Mark4 7-inch frame per the manufacturer’s instructions.
    • Install the iFlight XING E Pro 2207 motors (4x) and secure them to the frame.
    • Mount the SpeedyBee F405 V4 FC + ESC stack centrally, ensuring access to UART ports.
    • (Optional) Install the GEP-M10Q GPS module for enhanced tracking.
    • (Optional) Print cases for SSC30KQ and GPS module. STL files are available here.

  2. Video and Connectivity:

    • Mount the SSC30KQ camera with a 1.7mm lens, ensuring a clear forward view.
    • Connect the camera to the flight controller’s UART port (e.g., UART2) for CRSF telemetry.
    • Secure the DC-DC buck converter to step down battery voltage to 5V for the camera and modem.
    • Install the Quectel EC25 4G modem and connect the 4G FPC antenna for optimal signal.

  3. Power System:

    • Connect the 3S/6S battery to the ESC via an XT60 connector.
    • Wire the buck converter to power the camera and modem (5V, 3A output).
    • Ensure all connections are insulated to prevent shorts.

  4. Wiring:

    • Use the diagram below for connections:
      • Camera ↔ Flight Controller: UART (TX/RX) for CRSF protocol.
      • Modem ↔ Camera: USB for data.
      • Buck Converter: Battery → 12V input, 5V output to modem.
    • Secure wires with zip ties to minimize vibration damage.
Wiring
  1. Testing:
    • Power on the drone and verify the flight controller boots correctly.
    • Check camera connectivity (or flash it first) via the OpenIPC web interface (default IP via DHCP).
    • Test modem connectivity by inserting a SIM card and confirming 4G/5G signal.
    • Attach Gemfan Hurrikan MCK v2 propellers (check rotation direction: CW/CCW).

Notes

  • Ensure all components are securely mounted to withstand vibrations.
  • Use high-quality soldering for reliable connections.
  • Verify battery capacity matches your flight duration needs.
  • For detailed wiring, refer to the SpeedyBee F405 manual and OpenIPC documentation.
