The plug is about the same size as the socket, and slightly different inside. I've put up some pictures at http://www.flickr.com/photos/kylegordon/sets/72157623168052562/ - the new mini at the bottom, the original in the middle, and the board at the top. I downloaded the USB specifications from http://www.usb.org/developers/docs/usb_20_122909-2.zip and discovered in Micro-USB_1_01.pdf that the micro-A plug is 6.85mm by 1.8mm, and the micro-B is 6.85mm by 1.8mm, with chamfered edges. This damned thing is 5mm by 3mm. I couldn't find the designs specs for the mini-USB plugs, but from all the photos and the many that I have here, the mini-USB plugs are much larger, and all have chamfered edges. Sod it, I'll just solder the cable on :-( Well, it didn’t turn out to be a mini USB. The plug is about the same size as the socket, and slightly different inside.

Same name, different form factor. Clever stuff... :-/ A cable is only 3 quid on ebay, so I'll head down that route. It's to be connected to a computer by USB instead of a microcontroller, so I have to stick with having a plug on the other end. Hardwiring a cable onto it was going to be the last solution :-) mgdm gave the game away when he linked to http://www.cypressindustries.com/mini_usb_4p_connector.html It would seem to be a mini USB 4P variant.

Why not just do away with the silly proprietary connector and hardwire a cable on? Do you even need the USB bit if you're connecting it to a microcontroller? Too many pins for mini-B.

As opposed to the mini-A type that is in the same picture. It’s a mini-B type. As opposed to the mini-A type that is in the same picture. ]]>
