I've been wanting controlled playback of mp3s with a Picaxe for quite a while now, I've seen the 4D Somo module but looking around for other modules I discovered this one which is less than half the price:

It's larger at 51mm x 21mm, needs more voltage (6v-12v) and uses a normal SD card instead of the micro sized. The specs seem a bit sparse, no details on why it has both RX & TX when it doesn't say what information the module can send out, just what input control commands it has, but otherwise looks fairly simple & straightforward to use. I do wonder what all the other unnamed connection pins are for.
I ordered a couple and a couple of 1GB SD cards, altogether worked out about the same as a single Somo module without a card, when they arrive I'll post back with my findings on how I got on with them.
