4G LTE Industrial Mini PCIe to USB Adapter W/SIM Card Slot USB 2.0 4PIN PH1.25 Connector for WWAN/LTE 3G/4G Module

Overview Advantages Compatible with all 3G、4G wireless modules in the market, such as HUAWEI, ZTE, AIRCARD, LONGSUNG, YUGA, QUECTEL, MEIG, SIMCOM, SAMSUNG, HUAYU, DTT etc. Can be used for testing module as well as WiFi module (USB bus) and Mini PCI-E interface card (USB bus) via USB connector. To guarantee the module can always be working fine and never be offline even under severe environment, this adapter adopted the industrial level electric circuit design, one DC-DC power chip and two external tantalum capacitors. As we might know, when signal is unstable or weak, modules will consumpt much more power especially for 4G modules. But if we still use normal LDO chip, the 4G module will be offline because it cannot meet the request of power consumption of 4G module at that time. Working principle: the interface definition of Mini PCI-E is USB signal and 3.6V, the input voltage 5V by USB will be converted into 3.6V via DC-DC power chip to power on module and UIM/SIM card. (The working
