USB to minipcie network card - RTL8812/MT7612

The MINI PCI-E standard of notebooks and small hosts contains USB signals and 3.3V power supply. This project is to lead the USB signal to the network card module. Because the output of minipcie itself is 3.3v power supply, there is no need to make any adjustments to the power supply. In other words, this solution does not require any peripheral circuits and only exists as an adapter board.
Look at the working principle above. Because the USB signal is output from the computer, some computers screen this signal or have no signal output at all, which will cause this card to be unusable. If you encounter this problem, you can search for tutorials to unlock the USB port by brushing the whitelist.
Reserve full-height pcie, and you can cut it into half-height if necessary. (The board is 1mm thick and can be cut open with scissors or finger cutters. It's very easy.)
This packaged module (pictured below) generally has an IPEX antenna seat. If necessary, you can also change the pcb file by yourself, lead out the antenna signal, and change it to other antennas (note that the onboard antenna is not recommended. The signal in the machine is so bad that you can't imagine it. Even some metal-body computers are basically a Faraday cage inside! Signal... Haha.)
To be verified.
Because the minipcie interface only has usb2.0, this card can only use the usb2.0 version, and cannot fully utilize the transmission capacity of chips at the level of RTL8822. In addition, you can buy a pretty good minipcie network card for more than 40 yuan (the following picture, only 40 yuan including shipping, and also has Bluetooth function). The efficiency and stability of products designed by professional teams are not comparable to those made by this kind of personal hand, so this only provides a possibility (which means that almost all USB devices can be integrated on this minipcie card and used internally.), if not necessary, this solution is not recommended.
Note that the minipcie board is 1mm thick, be sure to check it accurately, otherwise it cannot be used!
