This is your standard USB A-Plug to Micro-USB cable. It's 2 meters long so you'll have plenty of cord to work with for those longer extensions. Perfect for connecting to your Raspberry Pi, Arduino Leonardo/Micro, FONA or Trinket (among other things). It's got extra beefy 24 AWG power wires so it works great for high power (1-2 Amp) computer powering.
If you want something a little shorter, check out our 3' USB-A/Micro cable.
