Sound Break Out

The bottom of my EZb V4 looks different slightly from the video I watched here for adding a 3.5mm jack. The ground hole is the same but there is only one hole with the gold colored surround in the area where I would think the power wire goes but Just want to make sure because it is slightly different from the video. Is this the spot where I would solder too?

I just got my V4 in January 2016.

Thanks for the help

So Left channel to Via and the ground to the common/shield tab correct?

yeah - if you get ground from the battery or before the EZ-B, will reduce any noise.

What do you mean? (I am not experienced with electronics) Are you saying not to use the ground port on the v4 like in the tutorial?

I used the EZB ground connection and wired the single audio channel output to both L & R connections.

Did you just a jumper to connect the L & R connections on the jack?

yeah the L and R of your audio connector can be connected together.

When i mentioned where to connect the GND - that can be the "black" or "gnd" at the battery, or the power pin of the EZ-B.

GND is also called "Common". This is because all devices can have different Positive Voltage, but they all must share a common ground. For example, in your house, ever breaker/fuse for every plugin is different - but the ground is the same. It's a common ground because everything needs that common ground. The earth is pretty much the biggest common ground you can find:D

Thank you for the help! This is all new to me and I don't want to screw up my EZ-B. Appreciate you explaining it in a simple manner.
