Indicator color：red/yellow/blue/green/white/pink/Total orange7Color options，You can also customize multi-color matching。

Diameter of two fixing holes3mmspacing100mm；

Signal input amplitude：300mV - 5v（Don't get too strong a signal）；

supply voltage：direct8v-12v；

zuilarge current：about70mA；

Function introduction：Two buttonsS1andS2，Long press（greater than1second）And short press（greater than0.2Seconds less than1second）The following introduction does not explain that long press means short press。

S1It is used to adjust the strength of input signal in normal display mode，Press repeatedly to decrease some input signals，Press tozuiIt will automatically return to the beginning，S1In brightness adjustment mode, click to increase the brightness by one level untilzuihigh。

S2It is used to select the display pattern in normal display mode，It's also a loop. Click to change one，reachzuiThe next one automatically returns to the second one-individual，S2In brightness adjustment mode, click to decrease the brightness by one level untilzuilow。S2In normal display mode, long press will enter brightness adjustment mode，S2In brightness adjustment mode, long press will save brightness and return to normal display mode。

Notes on wiring：

1、You can't use AC power，Don't connect to high voltage

2、-/+The label represents power supply，-Represents the negative pole of input power supply，+Represents the positive pole of input power supply；

R/L/GThe label represents the audio signal input，R、L、GThe three letters represent the right channel signal respectively、Left channel signal、Signally（That is, the negative pole of the circuit board power supply）；

3、The signal strength should not be too high，The signal strength provided by the general earphone socket is OK，Don't connect the amplifier. The output signal is too strong，The circuit may be damaged。
