Definition: Micro USB Cable - Type B
The term USB stands for "Universal Serial Bus", which describes the general communication format that each cable uses. USB cable assemblies are some of the most popular cable types available and are used to connect computers to peripheral devices like microcontrollers, keyboards and mice, printers, and more.
USB cables are supplied with many different connectors at the each end of the cable. These ends give each USB cable their respective name. Many of the USB cables used in Tech-Box.io kits utilize cables which have both a USB Type A plug and USB Micro Type B plug, giving them their name: Micro USB -Type B Cables. The Type A plugs typically connect to most PC's USB ports while the Micro Type B connector is used to interface with the ESP8266 NodeMCU board.
