AVATAR GT KIT QUICKSTART GUIDE V1.1

Introduction

This guide provides essential information for setting up and using the Avatar GT Kit.

Connection

Connect the components as follows:

Note: Power consumption is approximately 12V@1.5A. Please ensure your power supply has sufficient capacity. The VTX generates significant heat during operation; ensure adequate airflow for cooling.

Linking

1. Connect the VTX and goggles to their respective power sources.
2. Short press the link buttons on both the VTX and the goggles. The VTX will enter pairing mode, indicated by its LED turning solid red, and the goggles will emit a "DI...DI...DI..." sound.
3. Upon successful linking, the VTX LED will turn solid green, the goggles will stop beeping, and video output will be displayed.

Upgrade

To upgrade the firmware, download the latest firmware file (e.g., Avatar_Sky_X.X.X.img) from the official website. Ensure the filename is not changed.

1. Copy the firmware file to the root directory of the VTX's Micro SD card. Connect power and wait for the device to start up. Delete any old firmware files if present.
2. Press and hold the VTX link button for 8 seconds. Release the button after the indicator light turns off. The VTX will automatically restart and enter the upgrade state. The indicator light will change from blinking red to solid red, then turn off. The upgrade process takes approximately 20 seconds; do not power off during this time. If the VTX remains solid red, it indicates that the firmware was not detected or is incorrect; please verify the firmware file.
3. After a successful upgrade, the VTX indicator light will turn solid green and blink.

Note: The Avatar GT Micro SD card slot does not have a spring-eject function. Please apply the provided PVC sticker to the TF card before inserting it.

UART

The UART function allows the VTX to communicate with the flight controller, enabling flight controller OSD information to be displayed. The following describes the UART setup method using Betaflight Configurator as an example.

1. Solder the white and gray wires of the 4-pin cable to the flight controller's UART port (refer to the Connection diagram). This example uses UART1.
2. Connect the flight controller to Betaflight Configurator. Open the corresponding UART port (e.g., UART1), check the MSP switch, and click Save.
3. Open the CLI command line and enter the following commands (shown in red font in the original document):
   set osd_displayport_device = MSP
set displayport_msp_serial = Y (where Y is one less than the serial port number; for example, Y=0 for UART1, Y=2 for UART3)
   save

Betaflight 4.4 or above version settings:

1. Open the corresponding UART port (e.g., UART1), check the MSP switch, and select 'VTX(MSP+Displayport)' as the peripheral. Click Save.
2. Open the CLI command line and enter the following commands:
   set osd_displayport_device = MSP
set vcd_video_system = HD
save

Status Indication

Precautions

• Before powering on, please install all antennas to avoid damage to components.
• When standby mode is enabled, the power is limited to 10mW. Before takeoff, you need to unlock the flight controller or turn off standby mode.
• If you use it with other 5.8GHz devices simultaneously, please choose a different channel.
• If you use the Gyroflow function of the camera, please provide shock absorption for the camera's fixed mount to avoid anti-shake failure.
