关闭电源后，电源指示灯呈半亮状态，这正常吗？
答：这是正常的，这个指示灯有2个作用，作用1是指示5V总电源，作用2是指示并口电平输出，
若完成学习板的使用后没断开并口线，它会作出半亮指示，若短时间内要经常使用学习板，关闭电源开关即可。
此时，不需要拔下并口和串口，指示灯的半亮状态不会影响学习板的使用。-After the closure of the power, the power indicator light is bright, is this normal?Answer: This is normal, this indicator has 2 effects, action 1 is indicative of 5V total power, action 2 is directed parallel output,If completed learning board after the use of parallel lines are not disconnected, it will make the semi bright instructions, if a short period of time to often use the learning board, turn off the power switch.At this time, do not need to unplug the parallel and serial port, indicating lamp semi bright state does not affect learning board using the.
