?12 PIN接口（0.5mm间距）
Pin No.	Signal Name	Type	Description
1	VDD1	Input	Power supply: 4V to 5.5VDC, the typical is 5VDC
2	VDD2	Input/output	Power supply: * to 3.45VDC, the typical is 3.3VDC;  Or 3.3V output (max 100mA output current) when VDD1 is 5VDC input
3	GND	Input	Power/** ground: 0V reference
4	RX	Input	Serial data receive input port,3.3V TTL
5	TX	Output	Serial data transmit port, 3.3V TTL
6	USB_D-	Input/ Output	USB_D- **
7	USB_D+	Input/ Output	USB_D+ **
8	Power_en/
Ext_input	Input	Power_en or ext_input, please choose your needed type.
Power_en: the high level shut down the model, the low level turn on  the module, the high level turn off the module, the function only work when vdd1 power input.
Ext_input: can be used as external input such as external trigger control input or other input.
9	BEEP	Output	Beeper output control pin, the logic high indicates to open beeper, the driving current is 20mA.
10	LED	Output	LED output control pin, the logic high indicates to open LED, the driving current is 20mA
11	Ext_output	Output	External output: can used as external illumination or other output indication; support PWM or GPIO mode
12	TRIG	Input	Hardware triggering line, driving the pin low more than 10ms causes the engine to start to capture the image and decode.
Note: About power supply there are two application case,case1:VDD1 is 5VDC input and VDD2 is used as 3.3V output or null; case2: VDD1 is null and VDD2 is 3.3VDC input.

Power_en: the high level shut down the module, the low level turn on  themodule.
Ext_input: can be used as external input such as external trigger control input or other input.

?模块视场角
水平视场角：72°
垂直视场角：58°
对称视场角：85°
扫描窗口计算方法如下：当扫描距离是10cm,则扫描窗口14.5cm(水平) * 11cm(垂直)。
