I was looking around some listing on components and found this Bluetooth Interface module
its one third the price of the typical HC-05 modules, which got me interested. But, i could not find a lot of information about how to use it. Plus, i noticed a big difference on how it looks as opposed to the common modules, this doesnt seem to have the chips for a typical bluetooth...
So it got me wondering..
1.) Does anyone here know how to use this?.
2.) how to use it?
3.) does it need something else to work? (some not so common items)
4.) and any links for a tutorial?...
