hi, i hope i can get help here, i pulled this module from a bluetooth car hands free device (Supertooth one), and it has solderpoints all round it, see pic:
its labeled as btmm3c2xxv13 butt hat yealds nothing on google..
only pin i have identified so far has been the antenna (as marked)
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.
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.
