Not sure... probably a custom PCB. The chip of the left ("csr") is the bluetooth module, the other one (spansion) is the flash memory, probably for configuration stuff and such.

Anything on the flip side? I'm thinking this could be a custom PCB, therefore there would be no pinouts or datasheets available...

Yep. No markings, so most likely custom. If you want bluetooth, get a premade and tested one from a commercial outlet like sparkfun or little bird.

well i have identified the usb, grounds, antenna, and wat i beleve to be the uart rx/tx pins,
still working on it wen i got time, but hopefully if im successful and others find these units i hope to have documented the pinouts or at least a starting point to at least get them going.
