Montado con 4 hilos, lo puse en modo AT pulsando el botón inmediatamente después de encender el modulo, aunque no respondía a todos los comandos como: AT NAME? Mas tarde descubrí que pulsando el botón justo antes de enviar el comando si lo hacia.

Like you can view in my video http://www.youtube.com/watch?v=O0rgMZZxKPc SKU106872 is good ad really easy to connect with arduino. I also tried product SKU094617 which is also good. Both products are good and work with Arduino. This SKU106872 is my favorite. (Connection easy)

Received today and didnt tested... but the version I received is a little different from the photo. Mine have a different pinout (GND and VCC are in different places, for example, other pins have different names). Item is "naked", I mean not protected by a plastic envelope. Please update the photo and description, if you have changed version.

There seem to be minor differences on how to access these for programming. The easiest way to put it into AT "Command Mode" is to hold the button while powering up. This brings it up at 38400 baud even though it may be programmed to a different rate when it is in the normal mode. You could also enable command mode after power up by putting +5V on the KEY pin (EN) on this module but the baud rate will be as it is programmed. You should see a slow flash of the LED(as compared to when it is normally powered). Set a terminal for 38400 baud. Make sure the terminal is set to issue a carriage return and line feed. AT should work now. You may have to try it more than once to wake it up. It is normal that not all of the connections along the two sides and end are not soldered.
