As always google is your friend. There is the start (schematic only at the moment) of a Fritzing part here:
http://fritzing.org/projects/esp8266-connection-to-a6-gsm-module
If you want breadboard you (or someone) would need to make one, for which you would need the dimensions of the board (a quick search didn't turn up any documentation on the board only the A6 module itself which is on the board).
