Adafruit Product Code: 2910
This super slim, super tiny, and super cute Micro-B to USB on-the-go adapter is so slim, tiny, and cute that we'd pinch its cheeks if it was big enough to have cheeks. At just ~15.5mm long, ~11.3mm wide, and ~2mm, this really is the tiniest little adapter we've probably ever seen.
But don't let the size fool you - this is a perfect and easy way to turn a device or cable with a USB-A to a USB-micro, great for use with OTG devices such as phones, tablets, mini computers, Arduino Zero's, Raspberry Pi Zeros, etc. Just push it into the slot of a USB-A plug and, ta-dah... microUSB!
