IFlight BLITZ 5.8G VTX 1.6W Video Transmission 25mW/400mW/800mW/1600mW 30.5*30.5/M3 LongRange For RC DIY FPV Racing Drone                                                                              Basic parameters:               VTX power: 25mW/400mW/800mW/1600mW               Installation hole: 30.5*30.5/Φ3               Antenna interface: MMCX               VTX Protocol: IRC Tramp               Weight: 18.9g                              Precautions for use:               When installing the VTX, there must be space left to ensure air convection around the module to ensure module heat dissipation; otherwise, the module overheating protection will be activated, reducing power transmission, or even turning off power transmission.                It is recommended to ensure the correct voltage range and correct positive and negative poles before turning on the power, so as not to burn out the components.                It is recommended to make sure that an antenna has been installed at the RF output end before turning on the power, which can prolong the service life of the VTX module.               Remote operation OSD parameter adjustment instructions (serial control parameter adjustment) (IRC TRAMP protocol)               The VTX power levels of the flight control OSD are 25, 200, 400, and 600, corresponding to the local transmit power: 25mW, 200mW, 400mW, 600mW.
