3. Attention
- Please keep enough space when you install the VTX to ensure air convection around the module for heat dissipation. Otherwise, the module will enable overheat protection and the power transmission will be reduced or even switched off.
- It is recommended to ensure the correct voltage range and the correct positive and negative polarity before switching on the power to avoid burning the components.
- It is recommended that before switching on the power, make sure that the antenna has been installed; it can extend the life of the module.
- Please read the instructions for proper wiring before use.
LED Indicator and Function Button
Power Button
Press and hold for 2s: Enter or exit PIT mode, solid green light indicates entering PIT mode.
Green light (output power): The LED flashes indicate the VTX output power. 1 flash = 25mW, 2 flashes = 100mW, 3 flashes = 200mW. [Short press] to change output power.
Band and Channel Button
Press and hold for 2s: Blue (BAND) LED flashes indicate the Band A to R. Press and hold for 2s to switch Band.
Red (CH) LED flashes indicate the channel 1 to 8. [Short press] to switch Channel.
Frequency Table
Note: Antennas must be installed BEFORE powering on. The VTX can be damaged when using without proper cooling.

Connect VTX to FC
Diagram Description: Shows a Flight Controller (FC) and the BLITZ 1.6W VTX. The FC has pins labeled VBAT, GND, RX, TX, 5V OUT. The VTX has corresponding pins. The connection is shown as: FC TX to VTX RX, FC GND to VTX GND, FC 5V OUT to VTX VBAT, FC Video to VTX Video.
Note: Enable the corresponding VTX IRC Tramp on UART port in the FC configuration.
VTX Board Description: The VTX board has labels for VBAT, GND, RX, 5V OUT, GND, Video. It also shows the MMCX connector and the Band/Power and Channel buttons.
Connect VTX without FC
Diagram Description: Shows connections for Battery and Camera to the VTX.
Battery Connection: VTX VBAT connects to Battery positive (7-34V), VTX GND connects to Battery negative.
Camera Connection: VTX Video connects to Camera Video, VTX GND connects to Camera GND. The VTX also has a 5V output, but its connection to the camera is not explicitly shown in this diagram, though a 5V pin is present on the VTX.
VTX Board Description: The VTX board has labels for VBAT, GND, RX, 5V OUT, GND, Video. It also shows the MMCX connector and the Band/Power and Channel buttons.
