3.3v USB Cable? What are you using?

[Nomadic.Homebody]

I got my order yesterday (O2 + Arduino), but I discovered it needs a 3.3v cable.
Standard USBs are 5v and I don't want to short-circuit it.

Any recommendations?

Hi, hope this helps:

The MicroUSB Port receives 5V power and uses it directly to power the ATmega328P chip. The Dock comes equipped with a voltage regulator to step the voltage down to the required 3.3V for the Omega.
