The HC05 has spare I/O pins that can be controlled by AT commands.I guess that's not going to be suitable for time-sensitive communications, but it should be far enough to read on/off sensor data or control a relay for example.
So, I was wondering if there were a board available where to solder the HC05, including connections for its spare I/O pins?
I'm sure there isn't, and it's down to you to make your own. Itead have a standard shield with a prototyping area but I don't suppose it fits the definition of breakout board, although it may be adaptable to access the i/o pins..
edit
I have just seen a Bluetooth Bee 2.0. I know nothing about it but it is an HC-05, all the contacts thereon are soldered , and it has far more pins than the regular JY-MCU. I think it might be what you want.
