产品名称：Mini PCI-E转USB接口 3G模块开发板
注意：此款为无线网卡转接卡而已，不是3G无线上网卡，单插SIM卡时是不可以上网的，要同时插上带3G功能WIFI网卡才支持上网.

新版本产品特色：

1增加了固定模块的锁扣，以便用户安装方便及提高模块工作的可靠性及稳定性.

2 PCB增加了4个螺丝孔，以便此转接卡可用于工控小机箱内部。

3.增大SIM卡座和后排元器件距离，以便用户拆装SIM卡更加方便

4.增加USB 4线输入孔盘，可直接焊接USB线

工作原理：Mini PCI-E52pin接口定义有USB信号及3.3V电压，该转接卡是将USB接口5V电压通过LDO芯片转换为3.3V,供给模块及USIM/SIM工作，信号总线为USB信号

规格描述：

1.产品尺寸规格：85*31mm

2.Mini PCI-E设计符合1.30版本行业规范

3.USB设计符合USB 2.0行业规范，向下兼容1.1规范

4.此转接卡适合全高尺寸（30*50-51mm）WWAN/3G/WiFi等模块(USB总线)，
5.工作状态LED实时显示

6.产品无需任何软件驱动

用途说明： 该产品既适用于很多品牌的3G模块，如HuaWei、ZTE、AIRCARD、OPTION、SAMSUNG、华域、大唐等品牌3G卡，用于通过USB口上网及3G模块的刷机、调试、测试及解锁，也可以用于USB总线的WiFi模块（USB总线）以及Mini PCI-E接口卡（USB总线）通过USB来测试。

特别声明：本产品为转接口，MINI PCI-E转成USB的，不是3G网卡，本产品不含3G模块，如果没有3G模块，是无法上网的！本转接口主要用来DIY或者测试3G模块用，本组件不含外壳。Product Name: Mini PCI-E to USB interface 3G module development board
Note: This is a wireless card adapter only, not a 3G wireless network card, single SIM card can not access the Internet, to simultaneously plug in with a 3G function WIFI network card to support the Internet.

New version Features:

1 added a fixed module of the lock, so that users can easily install and improve the reliability and stability of the module.
2 PCB adds 4 screw holes so that this riser card can be used inside a small industrial control cabinet.
3. Increase the distance between the SIM card holder and rear components so that the user can disassemble the SIM card more conveniently
4. Add USB 4-wire input hole plate, can be directly welded USB cable

Working Principle: The Mini PCI-E52 pin interface is defined with a USB signal and a 3.3V voltage. The riser card converts the 5V voltage of the USB interface to 3.3V through the LDO chip and supplies the module and the USIM / SIM. The signal bus is a USB signal
