As technology changes and adapts, so does Adafruit, and speaking of adapting, this wee microadapter has a USB A jack (e.g. it will plug into a computer with an A port) and a USB C socket so your older computer or laptop can catch up to the latest USB Type C.
USB C is the latest industry-standard connector for transmitting data and power. Like Lightning and MagSafe cables, USB C has no up or down orientation. And who among us has inserted USB A correctly the first time?
Works great with any device that has a USB A socket and will let you attach a USB C cable. This adapter is low cost because it doesn't include USB 3 pins, so good for boards that don't need 3.0 speeds! Works best with USB 1 or 2. These adapters don't magically give you USB C speeds if you are using a USB 2.x port, and they won't give you the power negotiation stuff because your computer doesn't have that built-in. So it's strictly for devices that use 5V and up to 1A.
