When installing image transmission, it is necessary to leave space to ensure air convection around the module and ensure block heat dissipation.2. Before connecting the power supply, ensure that the correct voltage range and positive and negative poles are correct to avoid burning out the components.3. It is recommended to ensure that the RF output terminal has an antenna installed before connecting the power supply, which can extend the service life of the module.4. Please read the instruction manual before use, as this will enable correct wiring and extend the lifespan of the module.Package List:1 * 5.8G 4W 56CH VTX
