5. Guia de configuració
5.1 Muntatge de la pila
- Ensure your drone frame has a 30.5x30.5mm mounting pattern.
- Place the silicone grommets into the mounting holes of the ESC and then the Flight Controller. These grommets are crucial for vibration dampening, ensuring stable gyroscope performance.
- Carefully stack the ESC and Flight Controller, aligning the mounting holes.
- Secure the stack using the provided M3*25 or M3*30 screws and nylon nuts. Do not overtighten to avoid damaging the boards or grommets.

5.2 Connexions de cablejat
Refer to the wiring diagrams specific to your drone frame and peripheral components. Below are general guidelines:
- Connexió d'alimentació: Solder the XT60 power cable to the main battery pads on the ESC. Ensure correct polarity (positive to positive, negative to negative).
- Connexions del motor: Solder motor wires to the corresponding motor pads (M1-M4) on the ESC. Verify motor order and direction in BetaFlight.
- Flight Controller to ESC: The FC and ESC are designed to stack directly, minimizing wiring. Ensure the pin headers are correctly aligned and seated.
- DJI Air Unit: Use the provided DJI Air Unit Adapter Cable to connect directly to the dedicated port on the Flight Controller.
- Receptor (RX): Connect your receiver (e.g., Crossfire, ELRS, FrSky) to an available UART on the Flight Controller. Configure the correct serial protocol in BetaFlight.
- Càmera: Use the camera connection cable to wire your FPV camera to the FC's video input and OSD pads.
- GPS (Optional): Connect GPS modules to an available UART, ensuring correct TX/RX connections.
- Condensador: Solder the included capacitor to the main battery pads on the ESC to help filter electrical noise.
5.3 Firmware Flashing and Configuration
- Install BetaFlight Configurator: Download and install the latest BetaFlight Configurator software on your computer.
- Connexió al PC: Connect the Flight Controller to your computer using the Type-C USB cable.
- Firmware flaix: In BetaFlight Configurator, select the correct firmware target (GEPRCF405) and flash the latest stable firmware.
- Configuració inicial: After flashing, connect to the FC. Perform initial setup including accelerometer calibration, port configuration (UARTs for RX, GPS, VTX), receiver setup, and ESC protocol (Dshot 600 recommended).

- Sense canal de vídeo: Check camera connection, VTX power, and VTX/VRX frequency settings. Ensure DJI Air Unit is powered and connected correctly.
- Vol inestable: Re-calibrate accelerometer in BetaFlight. Check for loose components, damaged propellers, or excessive vibrations (grommets are key). Review PID tuning if necessary.
- Problemes de connexió USB: Try a different USB cable or port. Ensure BetaFlight Configurator is up-to-date. Reinstall VCP drivers if needed.
- Receiver Not Connecting: Verify receiver wiring to the correct UART, ensure correct serial protocol is selected in BetaFlight, and confirm receiver is bound to the transmitter.
9. Consells d'usuari
- Always use the provided silicone grommets during mounting to effectively reduce vibrations and improve flight performance.
- When connecting the DJI Air Unit, ensure the adapter cable is fully seated to avoid intermittent connection issues.
- For optimal performance, keep your BetaFlight firmware updated to the latest stable version.
- Consider adding a low ESR capacitor to your power input for cleaner power, especially with higher cell count batteries or powerful motors.
- Double-check all solder joints for cold joints or bridges before applying power.
