Sometimes you just can't avoid using a breadboard. As messy as they are, to test out circuits quickly, this is the best way.
But powering the breadboad so you have the right voltages used to be a sticking point.
Until a few years back when cool little modules like these started popping up all over the place.
I initially remember seeing these on Kickstarter and they absolutely crushed it, it's just such a clever idea.
This little module allows you to easily add 3.3V and 5V rails to your breadboard project.
This kit you see here from Amazon, bundles together a quality breadboard, jumpers to connect to your Arduino and the power brick all in one little kit from Kumon.
Input power can be accepted from a standard barrel jack or USB.
So when it's time to start building your next great idea, you have to get yourself one of these!
Super useful, and for the price you can't beat it!
