Recently I bought a BT module from eBay which was very cheap. I didn't really noticed the image and I just bought it. When it came I couldn't find any holes to solder the headers. Also the specific module is pretty rare and I couldn't find anything.
Here is an image:
How do I wire up this chip?

2Are you able to post a clearer photo? If your camera has a close-up or 'macro' mode then it may help.Peter Bloomfield– Peter Bloomfield2015年03月01日 14:00:08 +00:00Commented Mar 1, 2015 at 14:00

You at least post a link to the item on ebay; the blur pict you linked to is totally useless currently.jfpoilpret– jfpoilpret2015年03月01日 14:04:02 +00:00Commented Mar 1, 2015 at 14:04

@jfpoilpret Not exactly useless, but it definitely needs improvement.Avamander– Avamander2015年08月23日 21:34:55 +00:00Commented Aug 23, 2015 at 21:34

From the picture you posted, i was able to google and find something called a BC04-B Bluetooth serial module. It looks almost exactly like yours, and I found a diagram on how to hook it up. BC04-B Bluetooth serial module
I also believe that these are the serial commands you can use with it... Bluetooth module serial commands

It could be HC-06 or HC-05 but they operate quite similarly.Avamander– Avamander2015年08月23日 21:34:12 +00:00Commented Aug 23, 2015 at 21:34
These Bluetooth modules are typically mounted onto another substrate, either the product board or a small PCB backplane which provides the pinouts and any additional circuitry like the pairing LED, and power- & signal-level management. They are readily available as HC-05 (master/slave) or HC-06 (slave only) with signals brought to through-holes or pins at the edge of the backplane.
