5.2 Wiring Diagram (General Guidance)

Refer to the specific wiring diagram provided by GEPRC for your flight controller model for precise connections. The following is general guidance:

• Power Input: Connect the XT60 power cable to the main battery pads on the ESC. Ensure correct polarity.
• Motors: Solder motor wires to the corresponding motor pads (M1-M4) on the ESC.
• Flight Controller to ESC: The FC and ESC are designed to stack and connect directly. Ensure the pin headers are correctly aligned and seated.
• Receiver: Connect your receiver (e.g., SBUS, CRSF, ELRS) to the appropriate UART on the FC. Refer to the FC's pinout for specific UART assignments.
• Video Transmitter (VTX): Connect the VTX to the designated VTX pads (Video In, 5V/9V, GND) on the FC. Use the provided VTX connection cable.
• Camera: Connect your FPV camera to the designated camera pads (Video Out, 5V, GND) on the FC. Use the provided camera connection cable.
• Air Unit: Utilize the O3 3-in-1 connection cable for direct connection to compatible Air Units.
• GPS/Other Peripherals: Connect any additional peripherals (e.g., GPS, LED strips) to available UARTs or dedicated pads as per the FC's pinout.

  • Confirm the drone is armed and throttle is above minimum.
• No Receiver Input:
  • Check receiver wiring to the FC (signal, 5V, GND).
  • Verify UART configuration in BetaFlight for the receiver.
  • Ensure receiver is bound to your radio transmitter.
• FC Not Connecting to BetaFlight:
  • Ensure correct USB-C cable is used (data capable).
  • Install necessary VCP drivers (ImpulseRC Driver Fixer can help).
  • Try a different USB port or computer.
