I have an Arduino with a motor shield and I use it to power 4 different DC motors.
Motors are connected to the shield through a screw terminal.
Since I am in the prototyping step, I am moving them around a lot, connecting and disconnecting them all the time, which means screwing and unscrewing the wires every time.
I was looking for a jack, so I can easily plug in-out. I was going to use the standard 2.1 X 5.5 mm coaxial power connector, however I'm wandering if there is anything smaller.
The flowing power shouldn't be very intense, it's a 12v with a peak usage just little above 1A.
