This USB Micro B icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,400 icons, all in the same style and quality.
The icon is a depiction of a micro USB B connector, head on. A rectangle chip with five pins coming out of the bottom is housed inside a angular case. The icon calls to mind a micro USB B connector, a common connector used for many devices and to charge cell phones.
