Connection Diagrams & Peripherals
ESC Connection
This section describes the primary connections between the flight controller and the Electronic Speed Controller (ESC). The diagram shows:
- Motor Signal Outputs: M1, M2, M3, M4
- Battery Input: BAT
- Ground: GND
- 5V Power Output
- LED Connection
- BOOT Button
- USB Port
Analog VTX & Camera Connection
This diagram illustrates connections for an Analog Video Transmitter (VTX) and an FPV Camera.
- Camera Connections: CAM, GND, 5V
- VTX Connections: VTX, GND, 5V, CAM, TLM (Telemetry), CUR (Current Sensor)
Receiver Connection
This section details how to connect various types of receivers to the flight controller. It supports serial-based receivers such as SPEKSAT, SBUS, and CRSF.
- General Receiver Connections: SBUS, GND, 5V, 9V, RX, TX, BAT, LED.
- UART Configuration: The document indicates specific UART ports (e.g., UART1, UART2) are used for serial receiver communication and require configuration in the 'Ports' tab of the flight controller software (e.g., Betaflight).
DJI Diagram FPV System
This section outlines the integration of DJI digital FPV systems, including the DJI AIR Unit Module, DJI O3 AIR Unit, and CADDX Vista.
- DJI System Connections: CAM, GND, 5V, RX, TX, SBUS, 9V, INPUT.
- UART Configuration: Similar to other serial receivers, specific UART ports must be configured for communication with the DJI system.
Configuration/MSP Settings
The document lists typical configuration settings for various peripherals via the Configuration/MSP interface, often using UART ports. Common settings include:
- USB VCP: 115200
- UART1: 115200 (often for Receiver or VTX Telemetry)
- UART2: 115200 (often for Receiver or VTX Telemetry)
- Other UARTs (e.g., UART4, UART5) are also shown with 115200 baud rate for receiver configuration.
- Telemetry Output is generally listed as 'Disabled' for most ports in the default configuration shown.
