Product overview
The Kimpok 3.3G 4W VTX is a video transmission component for integration into FPV drones and model aircraft. Its intended applications include racing, aerial photography, long-range flights and remote monitoring requiring real-time video. Sixteen selectable channels span 3170MHz-3470MHz within the 3.3GHz band. Output can be set to 25mW, 2000mW or 4000mW, giving three discrete power settings. Configuration uses button controls with LED status indicators, and IRC Tramp smart audio support provides a further control interface for integration.
The module measures 53×28.85×16mm and weighs 25.85g, with a 20mm×20mm mounting pattern and 2mm mounting holes. Its hardware configuration combines an aluminum alloy housing, heat sink and fan, so installation space must accommodate that assembly. Connections include an SMA female antenna connector and a 1.0 6-pin power connector with 5V output. It accepts DC 7V-36V and supports 2-8S batteries without adapters. Automatic thermal protection reduces output power above 100°C, making temperature a material limit on sustained operation at the selected power.
