The Walksnail Avatar HD VTX V2 is a replacement transmitter module for the Walksnail Avatar digital HD transmission system. It has mounting holes with both 20x20mm and 25.5x25.5mm spacing, making it easy to install into the drone frame. By redesigning the PCB and heat sink, the transmitter's durability has also been increased. There are also new solder pads for those who don't want to use a connector. Another big change from the first version is the increased integrated memory to 32GB. The transmitter can be powered by up to a 6S battery. A newly integrated TVS diode protects the transmitter from voltage spikes.
