This is a simple, inline adapter that you can plug into any standard USB A port, and plug a standard USB A cable into. This blocks the 5v power signal from reaching the other side. Use it on a 3D printer, CNC machine, or your custom Arduino and ESP8266 or ESP32 projects!
Various USB devices may be plugged into your computer or raspberry pi all the time. Sometimes you don't want these devices to receive power via USB. Why? You may want the power light or screen to only come on hen the device is turned on. You also may only want to use USB for communications, and not for powering your project.
Nothing! It's literally a USB A male to female connector without the 5v line connected. What you get is a neat little package that's ready to go!
