Nice contribution, thanks.
By the way I did a quick search on ebay for this type module and found a very nice one that already has terminal connectors and jacks and has an internal voltage regulator so you can power it from either batteries or external DC wall wart type power packs. It also has solder pads to make all connections via wires instead of the on board terminals and jacks, so it would still be easy to connect to an arduino. The price is just $5.78 with free shipping. I've bought from this ebay seller many times and have never been disappointed with any of their offerings. So I bought one.
