micro USB

Contributor(s): Matthew Haughn

Micro USB is a miniaturized version of the Universal Serial Bus (USB) interface developed for connecting compact and mobile devices such as smartphones, MP3 players, GPS devices, photo printers and digital cameras.

Micro USB connectors exist or have existed in three forms: micro A, micro B and micro USB 3. USB 3 micro is much like micro B, but with an additional pin group on the side for twice the wires, enabling USB 3's greater speed. Like standard USB, the micro versions are plug-and-play and hot-swappable

The USB peripheral bus standard was developed jointly by Compaq, IBM, DEC, Intel, Microsoft, NEC, and Northern Telecom. The technology is available without charge for all computer and device vendors.

See, below, illustrations of mini and micro USB versions:

Figure 2: USB mini and micro A and B

Mini versions of the USB specification that preceded the micro versions have since been phased out. The micro A connector was also phased out in favor of the thinner, sturdier B connector. Micro USB 3 ports can also accept standard B cables. To help with compatibility, some devices include an A/B dual port.

I watch my movies off of a USB in my TV set! Now I got a RCA tablet with MICRO USB port. Is there any way I can put movies on a micro USB from my reg USB? Sounds confusing but that's all I got! Any help would be great! Thanks.
