Bluetooth Modem

This is less of a "project" but a piece of hardware that fell of the internet, sort of a seed, that might evolve into one or the other project.

"Don't turn it on, take it apart! " (Dave Jones, host of EEVlog)

Hardware

Aipermon ​Bluetooth Modem HB300, found at ​Pollin for 1 € (190 left according to roh).

As on can infer from the 4th image, where the shielding of the bluetooth module has been removed, the ICs on module are:

• BC417 CSR Single Chip Bluetooth v2.0+EDR System (​datasheet)
• CSR29308 (?)

BC417 Block diagram:

As the ​post on mikrocontroller.net points out, there is a similarity of pinouts to the BTM112.
