FPV drone racers and builders, this video transmitter is packed with features for serious flying! Operating on the 5.8GHz frequency with 48 channels gives you plenty of options to find clear signals and avoid interference with other pilots. The adjustable output power is where this really shines - you can switch between PIT mode (ultra low power), 25mW, 200mW, 400mW, or 800mW depending on your needs and local regulations. The voltage input range of 3.7V-5.5V makes it compatible with various battery setups, and it provides 5V output (max 250mA) for powering your camera or other components. The compact 28x28mm PCB size with 20x20 M2 mounting pattern fits most modern racing drone frames, and at just 5.6g (without antenna), it won't significantly impact your build weight. The MMCX antenna connector is standard and reliable. It supports IRC Tramp protocol for easy configuration through your flight controller. The working current ranges from 150-550mA at 5V depending on your power setting. Whether you're building a new quadcopter or upgrading your existing FPV setup, having a versatile VTX like this with multiple power options and channel selection gives you the flexibility to fly in different environments and conditions. For DIY drone enthusiasts who want control over their video transmission quality and range, this transmitter delivers professional features at an accessible level.
