Hey guys, I'm trying to add a BlueTooth module to my desktop based on a guide I found online, and am in need of something similar or (preferably) exactly like this: The purpose is to lower the 5V output from an internal USB 2.0 header down to 3.3V in order for it to not fry the internal BlueTooth module. The original guide for making the BlueTooth assembly linked to an eBay ad (where I took the photo from) and it was listed as "DC-DC Converter Module regulator In:4.75-6V Out:3.3V", but the seller has since sold out so I'm forced to look elsewhere. What's important is that it has the two green securing mechanisms on both ends so that I don't have to solder (I neither know how nor have the tools). I've looked on Amazon, eBay, and the usual places I can think of but haven't been able to find that exact item. I'm no good with circuitry, so I'm wary about purchasing something that looks similar without advisement from some of the experts here. Does anyone here know where I can pick up something like this? Edit: I FOUND SOMETHING! Would something like this serve the same purpose?
