## Description

3-channel video switch for analog FPV systems, allows connecting three cameras to a single VTX and quickly switching between sources directly from the radio control. It operates at 4.8-6V, switching is done via PWM on proportional channel or 3-position switch, offers stable signal through high-speed switching chip, is compact and easy to mount on drone or aircraft model.
The PV3IN1 3-channel video switcher module for connecting three video sources simultaneously to the base station. This device allows fast and efficient switching between different video sources, being perfect for users who use multiple cameras on a model aircraft, drone or other equipment equipped with FPV cameras.
With the help of this module, for example, you can mount several cameras on a single VTX, being able to quickly switch between the cameras connected to the VTX that will transmit the video signal to the base station or analog glasses.
The module is interposed between the analog cameras and the VTX, it connects the cameras on demand to the VTX, the switching control is done either through a proportional channel (PWM) or through a channel with a 3-position switch, depending on the preferences and the configuration of the station your
It is equipped with a high-speed video switching chip, the module ensures stable switching.
Specifications:
Model: PV3IN1
Input voltage: 4.8-6V
Dimensions: 4.0 x 1.8 x 0.5 cm
Input channels: 3
Output channel: 1
Video signal impedance: 75Ω
Dimensions: 41 x 23mm
Net weight: 3g
Ports:
IN1, IN2, IN3: Inputs for the video signal
OUT: Output for the video signal

"S": The digital signal from RX, for switching between channels
Use:
Connect each camera to the input ports (IN1, IN2, IN3) of the module.
Connect the signal pin (S) to the RX of the radio control, preferably using a channel connected to a 3-position switch to switch between the connected cameras. If you use a 2-position switch, you will only be able to switch between two of the video sources.
Connect the module to a power source between 4.8-6V to ensure proper operation.
