I have to drive some high power LEDs (using TIP122 darlingtons), for a total current around 2 A on 12 V input. I'm wandering if I can drain this current from the V_in and GND pins of the Arduino Uno board, just connecting a 12 V supply to the Arduino board and using it to power both board and loads,…

How much current through V_in and GND pins?

Is is called a USB B to USB B adapter and I don't think they exist.
