What is it?

The Groudunio solves several inconveniences of using an Arduino Nano, most prominently adding 5 extra ground pins, 5 extra +5V pins, and pins for either 4 extra +3.3V pins, or a capacitor (2200uF fits nicely).

Why did you make it?

While there are lots of Arduino Nano screw terminal boards available, few if any feature the extra ground and power pins that allow you to complete a project without resorting to some sort of ad hoc connection method.

What makes it special?

Per Adafruit's Uberguide to NeoPixel LEDs, you're supposed to use a large-ish capacitor on the supply to avoid losing power to your microcontroller. This can be inconvenient, so those of us that are tech-rebels often throw caution to the wind and go without. With this board, you no longer have an excuse, as the solder points are built-in.

Alternatively, you can hook up the +3.3V pins next to it with either screw terminals or male headers, and in a pinch with some creative bending you can probably use both.

Finally, The screw terminals accommodate either 3mm screws/spacers, as well as 6-32 screws. Spacing is 1 1/4 inches between the holes, or ~32mm

Note that the base price is for the PCB only, screw terminal and capacitor assembly is available as an option, which will include female headers for the Nano. Two sets of 8 screw terminals may be substituted for single set of 16 screw terminals pictured. The Nano itself is not included unless selected as an option.

Depending on where it's shipped, you may owe import duties not included in price.

Very nice device

I bought the fully assembled package with a Nano. It was delivered quickly and works great.

Not only one can hook this up and leave it running something or a more extended period of time, it has extra power and a cap to stabilize the power where you use it for other part.

Handy to not have to build it out for me, as I'm not as well equipped as some. but I do have the parts and a small screwdriver to set things up.
