接口定義
Power and indicator
The power input interface is a 2PIN 2.0mm pitch female. Two pairs of 2PIN power supply holes are reserved on the board. One pair of power supply holes are directly connected to the power input signal, and the other pair of power supply holes are exposed after anti-reverse protection. This Encode board also provides a 5V power output interface, which is convenient for the user to supply power to the cooling fan when needed. The figure below shows the power pin signals and indicators.
LED1: Power operation indicator, always on after power-on;
LED2: Video signal detection lock indicator light, this Encode board will automatically lock after detecting the video source. If the LED is not lit, the system fails to collect the video source.
LED3: Video coding work indicator, flashing during normal operation.
