Using high-quality gold-plated connectors, high-frequency support USB3.0 stable transmission. The PCB is made of high-frequency and low-resistance high-quality materials, the PCB workmanship is precise, the PCB uses a high TG sheet, and the thickness of the copper material is thickened to 1oz; the gold-plated connector has good electrical conductivity, which can reduce the disconnection and speed reduction caused by the increase of oxidation and rust resistance. Problems such as lag and lag.The differential signal strengthens the layout design, there will be no CAF micro-short circuit phenomenon, the high-speed signal data transmission does not have the signal attenuation interference problem of parasitic capacitance and parasitic inductance, and the power circuit strengthens the wiring design.The miniaturized design of the PCB board can reduce the interference of the mechanism, and the hardware is not stuck, and the product is easy to install.The adapter board does not need a driver (the software driver of the M2 card must be installed) dual SIM card slot design, dual LED indicator design, does not support SIM hot swap.The design of the discharge circuit reduces the failure rate, and there is a gasket at the bottom of the adapter board to protect the product from being sturdy and durable.Item model number: WS16Product name: mini-PCIe to USB 3.0 riser cardWorking voltage: 3.0~4.6V (default 3.5V); 3A/4A (normal/peak current)Specifications: 3G/4G/5G/LTE M.2 NGFF key B module is transferred to the USB3.0 port of the computerProduct use: mini-PCIe supports transfer testing of full-height or half-height WWAN modulesColour: BlackMaterial: PCBSize: 10x4x2CMPackage Contents:1 * mini-PCIe to USB3.0 adapterOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
