Let's Break Down the key Features of this VTX:

Output Power Levels: The VTX supports adjustable output power levels ranging from 25mW, 100mW, 200mW, 400mW, up to a maximum of 600mW. This flexibility allows the user to choose the appropriate power level based on the flying conditions and desired range.

Frequency Bands and Channels: The VTX operates on the 5.8GHz frequency band and supports 40 channels. These channels are typically used in FPV systems, providing options for different frequencies to avoid interference with other pilots.

PitMode: The VTX features PitMode, which is a low-power mode designed for use when preparing for flight or when a quadcopter is on the ground. PitMode reduces interference with other pilots and allows for channel changes without affecting other pilots' video feeds.

Voltage Input Range: The VTX is designed to operate within a voltage input range of 7-26V. This makes it compatible with various battery configurations, from 2S to 6S LiPo batteries.

Adjustable Power Output: Users can manually select the desired power output level using buttons or other controls on the VTX, providing flexibility in adapting to different flying environments.

LED Display: The VTX likely features an LED display or other visual indicators to provide information about the current settings, such as selected frequency, power level, and PitMode status.

20x20mm Form Factor: The 20x20mm size is suitable for mounting on smaller-sized flight controller stacks, offering a compact solution for mini quadcopters or other small FPV platforms.

SMA Connector: The VTX is likely equipped with an SMA connector, a standard connector for connecting antennas to the VTX.
