Product overview
The Kimpok KP-T3340B provides an analog FPV video transmission component for racing-drone integration. Its 16 channels span 3170MHz–3470MHz, with selectable outputs of 25mW, 2000mW and 4000mW. The hardware combines an aluminum alloy enclosure, heat sink and fan in a package measuring 53mm × 28.85mm × 16mm and weighing 25.85g. Installation provisions include a 20mm × 20mm mounting pattern with ø2mm holes, an SMA female antenna socket and a 1.0 6P power connector. These dimensions and interfaces define the component’s mechanical and electrical integration requirements.
Power input is DC 7V–36V, supporting 2–8S batteries, while IRC Tramp provides a control interface. Local buttons select channels, bands and output power; red, blue and green LEDs identify those settings. Holding the power button for three seconds activates pit mode. Thermal protection limits sustained output: above 100°C, power steps downward and can reach 25mW if the temperature remains high. The original power setting returns when temperature drops to 95°C. The described configuration is a transmitter component with cooling hardware, rather than a complete flight platform or airframe kit.
