Features: Attention:The MINI PCIE standard of the laptop includes USB 2.0 signal and 3.3V power supply. This product extracts the USB signal from the USB HUB chip and boosts the voltages from 3.3V to 5V/1A to supply the USB device. Since the USB signal is output from the computer, some computer screens may cheat on this signal or have no signal output at all, which can cause the card to be unusable, not a problem with the card. If the internal bridge USB is damaged, this card cannot be used. You can search for tutorials on whitelisting to unlock USB port, so this product is suitable for users with computer setups. This product is only suitable for Mini PCIE interfaces applications, and other interfaces are not available!
