1.This adapter cable allows you connect any PCI-E device to Mini PCIe slot through a stand PCI-E 4X port.It's a debug,test and any other useful tool to extend PCI-Express slot from Mini PCIe slot. 2.Support Mini PCIe socket not only Half-Mini card but also Full-Mini card.Support 12V power by 4pin FDD power connector for Standard PCI-E device. If your device doesn't need 12V power input, you 't connect the attached power cable. 3.As PCI Express 4X connector is edge-free/multi-, 1X, 4X, 8X and 16X PCI-E cards are also available. The most matched type is 4X. But the speed will limit 1X because of the Mini PCIe speed limited.Using High quality wire, using High quality connector, high frequency support PCI-E 3.0 stable transfer. 4.No drivers needed for this Adapter.Supports Win XP, Vista 32/64, Win 7, Win 8, Win10, Win11 or Linux and so on.Supports PCI Express based MiniCard slot. If MiniCard slot on the host does not support PCIe interface it can not be supported. Other PCIe speed of PCIe2.0 (5Gbps)/PCIe3.0(10Gbps) is not guaranteed. 5.It's also a powerful tool for engineers, or use for PCI-E tester, extender and so on.Refer to PCI EXPRESS spec and PCI_Express_Mini_CEM_2_0 spec.
