4. Instal·lació i cablejat
4.1 General Wiring Diagram
This diagram illustrates connections for various peripherals including Spektrum, ELRS, PPM, SBUS receivers, LED strips, Servos, Buzzer, GPS, DJI Air Unit, and Analog VTX.
4.2 Connexió amb FC i motors
Nota 1: Per evitar que la pila es cremi pel voltage spikes on powering up, it is strongly recommended to use the Low ESR capacitor included in the package.
Nota 2: The FC and ESC can also be connected via direct soldering. Soldering pads definition is as follows:
- F405 V4 Flight Controller: Connects to BLS 55A 4-in-1 ESC via 8-pin cable or direct soldering pads.
4.3 Connexions del receptor
Avís d'importància per al receptor ELRS
We recommend connecting the ELRS receiver's TX and RX to the T2 and R2 pads on the flight controller. However, when using the DJI Air Unit simultaneously, some ELRS receivers may not be recognized properly by the flight controller. If you encounter this issue, you need to disconnect the SBUS signal wire from the Air Unit harness. You can use tweezers to pick out the SBUS wire from the 6-pin harness connector (or directly cut this wire) and insulate the exposed part of the wire carefully.
Avís d'importància per al receptor SBUS
When using an SBUS receiver, the SBUS signal wire of the receiver must be connected to the SBUS pad on the front side of the flight controller (this pad internally uses UART2). If you are also using the DJI Air Unit (O3/Link/Vista/Air Unit V1), you will need to disconnect the SBUS signal wire from the Air Unit harness. Failure to do so will prevent the SBUS receiver from being properly recognized by the flight controller. You can use tweezers to pick out the SBUS wire from the 6-pin harness connector (or directly cut this wire) and insulate the exposed part of the wire carefully. Do NOT connect this wire to assure the external SBUS receiver work properly!
4.4 Cable Connection vs DJI Air Unit
- Cable Connection vs DJI O3 Air Unit: Use 6-pin cable comes with the O3 Air Unit.
- Cable Connection vs RunCam Link/Caddx Vista Air Unit: Use 6-pin cable comes with the F405 V4 stack (See accessory No.11 in the package section).
- Cable Connection vs DJI Air Unit V1: Use 6-pin cable comes with the F405 V4 stack (See accessory No.11 in the package section).
