Mini or Micro? Mini or Micro??? Mini AND Micro! This is a handy USB cable, it's compact so you can toss it into your toolkit, and has both Mini-B and Micro-B connector. Now you can hook up your LiPo Charger or a Arduino Micro/Leonardo/Raspberry Pi using the same cable, sweet!Approximately 8" long from end to end, its a little more compact than our classic 3' long cableThis cable does not contain a hub, so you can only connect one USB device at a time (to either end). The micro end does data and power, the mini side only does power (not data)
