Adjusted description of one of the ICs on the BT module.

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)


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 (?)

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