MINIPCIE to USB

Overview

The MINI PCI-E standard of a laptop or small host contains USB signals and 3.3V power supply. This project is to lead the USB signal to the USB socket and boost the 3.3V to 5V/1A voltage to supply the USB device.
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. It is not a problem with the card. You can search for tutorials on brushing the whitelist to unlock the USB port.
A simple module, also sold on Taobao (see the picture below), is not technically difficult. With this project, you can make it yourself.
Unverified (the picture is stolen from someone else's product, whisper... I will definitely add it after verification.)
