Unless you've got the corresponding mappings to those header pins on that board, you may have issues. To be usable other than through the serial and the wireless portions of the device, you're going to need the pin map there. Units like the one on the bottom or ones modeled precisely after that have a just-so mapping that is clearly marked on the top of the circuit board. The module you show doesn't QUITE meet that requirement- and unless the vendor gives you a clear 1-to-1 mapping of the pins to the SoC's pinmux, you're left without means to use the pins right.
If you've got that info for this module it'll be fine- there's a clear mapping to the tutorials. If you're uncomfortable going there yet, don't have a good mapping, etc. you should probably stick with the Adafruit, Olimex, etc. devices which match the tutorials. They're readily available from the suppliers, even Amazon. While "more expensive", they're what's fully documented right now as best as I can tell. Unless you do this kind of stuff for a living (*waves hand*) why make your life harder?
