This new version of SparkFun's Mini-B breakout now has all 5 pins broken out on the connector.

We have no idea what USB device you are hooking up to, but if you need to add a miniUSB/USB Mini-B connector to your breadboard - here it is!

Also good for an un-regulated, non-limited 5V supply up to 100mA.

Mini-B USB cables are available here!
