The particular module that you have, I am unfamiliar with. It uses the same chip as the Parallax one, but the PCB layout is different. And the pins on yours do not seem to be labelled, which is unusual. And the two rows of pins together, are unsual. Easy enough to solder to something, difficult to mount in a temporary breadboard.
