GEPRC GEP-F722-BT-HD V3 Flight Controller

Specifications

ESC Connection

The flight controller connects to the Electronic Speed Controller (ESC) via multiple pins. These typically include:

• M1, M2, M3, M4: Motor signal outputs.
• CUR: Current sensor input.
• R5: Unspecified signal/connection.
• BAT: Battery power input.
• GND: Ground connection.

Diagram shows these pins on the FC connected to corresponding ESC inputs.

Camera Connection

The flight controller provides power and signal for a camera. Connections include:

• CAM: Camera signal/data pin.
• GND: Ground connection.
• 5V: 5V power output for the camera.

Diagram shows these pins on the FC connected to the camera.

Receiver Connection

The flight controller supports various receiver types, including serial receivers (SPEKSAT, SBUS, CRSF). Connections are made via UART ports and power pins.

General Connections:

• RX: Receiver data input to the FC (e.g., connected to receiver's TX).
• TX: FC data output to the receiver (e.g., connected to receiver's RX).
• 5V: Power output for the receiver.
• GND: Ground connection.

Configuration Notes:

• When using a serial receiver, configure the corresponding UART port on the FC to 'Serial Rx' (via the Ports tab in configuration software).
• Select the correct serial receiver protocol (e.g., CRSF, SBUS) from the dropdown list.

Diagrams illustrate connections to a generic receiver and mention specific protocols like CRSF.

DJI Digital FPV System Connection

This section details connecting DJI digital FPV systems like DJI O3 AIR Unit or CADDX Vista.

Connections:

• RX1 / TX1: UART connection for data communication (e.g., FC TX1 to DJI RX, FC RX1 to DJI TX).
• GND: Ground connection.
• 9V: 9V power output for the DJI unit.
• INPUT: Power input for the DJI unit (voltage range 7.4-26.4V).

Diagrams show specific pin assignments for DJI O3 AIR Unit and CADDX Vista, including power input ranges.

Analog FPV Connection

For analog FPV systems, the flight controller connects to the Video Transmitter (VTX).

Connections:

• TX: FC video signal output to VTX.
• RX: FC control signal input from VTX (e.g., for SmartAudio or Tramp).
• 5V: 5V power output for the VTX.
• GND: Ground connection.

Configuration:

• The UART port used for VTX control (e.g., SmartAudio, IRC Tramp) should be configured accordingly in the software. The diagram shows options like 'VTX, IRC Tramp' and 'AUTO'.

Diagrams illustrate connections to a VTX, showing TX/RX pins and power.

GPS Module Connection

The flight controller can connect to a GPS module for navigation and positioning.

Connections:

• GPS: Dedicated GPS data pin.
• TX: FC data output to GPS module.
• RX: FC data input from GPS module.
• 5V: 5V power output for the GPS module.
• GND: Ground connection.

Configuration:

• GPS modules are typically connected via UART ports (e.g., UART4, UART5).
• The corresponding UART port needs to be configured for GPS input in the flight controller software. The diagram shows options like 'GPS' and 'AUTO' for UART5.

Diagrams show connections to a GPS module, highlighting UART ports.

Buzzer Connection

A buzzer can be connected for audible alerts.

Connections:

• BZ-: Buzzer control pin.
• GND: Ground connection.

Diagrams show these pins on the FC connected to the buzzer.
