Advantages - Equipped with Quectel EC25-E IoT/M2M-optimized LTE Cat 4 module, which enables it be able to delivers maximum data rates up to 150Mbps downlink and 50Mbps uplink. Application - It can be widely used for quick network connection which enables you to let your PC connect to 4G network directly after installing matched Mini PCIe module(EXCLUDED) and corresponding driver. Reliability - It adopts industrial electric circuit design, DC-DC power chip and two external tantalum capacitors to make sure the module can always be working fine and never offline even under severe environment. Principle - The interface definition of Mini PCIe 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. Interfaces - There are Mini PCIe connector for connecting 4G LTE module, USB 2.0 (Type-C 3.1)connector, SIM card slot(Push-Push Type) which doesn't support hot-plugging.
