A. Functional Features With the spread of USB3.2, an increasing number of computer cases are equipped with TYPE - E or 19 - pin front USB interfaces and place them at the front of the case. However, some old motherboards do not support USB3.2 and do not have TYPE - E or 19 - pin interfaces. You can convert the PCI - E signal into a USB3.2 GEN1 19 - pin interface or TYPE - E interface through the M2 slot on the motherboard. In this way, you can connect the 19 - pin or TYPE - E interface on the panel to the expansion card, thus providing a front ultra - high - speed USB3.2 interface, which is relatively convenient. The main control chip uses a USB chip, the third - generation product D720202 from Renesas (NEC). It is one of the expansion cards on the market that can support the LINUX system. When in use, you need to insert the power interface. The expansion card uses inductors and capacitors, which helps ensure the stability of USB power supply. B. Hardware Requirements A motherboard or laptop that supports M2 KEY - M NVME is needed. This product is a PCI - E or NVME expansion card. It is recommended not to insert it into the M2 Sata slot. C.
