Oooh it's so soft! And that beautiful pattern! If you have to have visible cables then you might as well have the nicest fabric bound cable with a eye-catching snake-like pattern. That's why we now carry this standard A to micro-B USB cable for USB 1.1 or 2.0. Perfect for connecting a PC to your Arduino Leonardo/Micro, Raspberry Pi, NETduino, (among other things).
Basically: have something with a microUSB port? This will work, and it's 3 feet / 90cm long.
Note: While the covering pattern may change, the main color on the cable will always be Adafruit black
