Jim,

> I'd say there's enough info to get you going - at least for HW.

And as I've already tried to make clear, I absolutily disagree with you
there.

> Perhaps you didn't do sufficient research before you  bought?

True.  With the meager information the webshops page offered I assumed that
the rest of it would be provided with the module itself.   Thats not a
mistake I will easily repeat.

But tell me, as the breakout board itself does not have much, if anything,
to descern it from a multitude of other boards (all sold under the generic
HC-05 breakout board name) how would I find the information to it ?  What
would I need to search for ?

And as you might have noticed, I did such research - just afterwards instead
of beforehand - only to discover that none is to be had (or to be more
precise: enough "user generated content" floating around, but at times
conflicting with each other - making it inconclusive)

Which is why I asked here.


Bottom line: Even though I bought a breakout-board module enabeling the
HC-05 module to work with supply voltages between 3.6v and 6v it can't be
used (connected) in any way (to a 3.3v or a 5v MCU) without adding more
components*.  Which is not what I expect from a "use with different supply
voltages" breakout board.

*with the RPi as an exception, as it has 3.3v signal lines and a 5v power
output pin.
