The Live View encoder board is responsible for preparing digital video signal for live FPV feed. It encodes the video and sends the stream to WiFi board. It is part of the WiFi Module.
The board contains DM3xx series media processor which does the encoding and controls input and output lines. All other components on the board are just supplemental chips required by DM3xx to work.
Known versions of the board are shown below.
