Involvement:General (knows how to use it) - Ownership:1 week to 1 month
Price: *****
Ease of Use: *****
Build Quality: *****
Usefulness: *****
Overall Rating: *****
Pros:That module is very, very cheap and it works really good.
I do not know if the UART interface is TTL Compatible because I used with 3,3V voltage, but I think it coul be.
Cons:The Module can be configured with AT Commands but you only be able to change a reduced set of options.
The module can only act as a slave, so you can not connect modules together.
Other Thoughts:As said in the preview review, if you need a Master functionalitiy, you can flash an other Firmware on to the module..
The firmware can be found later on my website http://www.endasmedia.ch
Bottomline:It is a nice module but its a little bit bad that you only can change the PIN Code, device name and baud rate.
  It works :)

Pros:Pro is that the Module is very cheap and it works really good.

The UART interface is TTL Compatible because it is an CMOS input so you dont have to translate the voltage levels

The Module can be configured with AT Commands
Cons:You only be able to change the PIN with the AT Commands

The module can only act as a slave, so you cant connect modules together.

Other Thoughts:If you need a Master functionalitiy, you can flash an other Firmware on to the module..
