First, the working principle of the transfer board: EDP to HDMI adapter board, HDMI output resolution is to follow the motherboard output EDP signal, 40p adapter board output HDMI support 4K60HZ below the common resolution,30p maximum support 1080p60HZ. First, transfer board power supply principle: The power supply mode of the conversion board is powered by the EDP drive voltage. By default, the conversion board needs the EDP drive voltage to supply 3.3V, and the conversion board hardware also supports the 5-12V drive voltage. EDP input interface definition: 40PIN interface definition for 4LANE; It is the same as the common 4K screen interface definition on the market 2LANE 30PIN interface definition; It is the same as the definition of the common 1080P screen interface on the market Color: Green Material: PCB Specification: 40pin Package Contents: 1 * transfer board
