Broadcom BCM2042 Bluetooth HID

Could you make a breakout board for the Broadcom BCM2042 Bluetooth HID on-a-chip? I found this while trying to find a small solution for doing a bluetooth keyboard hack. It would make things really easy to send simple keypresses or mouse commands to a computer. According to your site, this is also the chip inside the wii-mote that handles the Bluetooth. It can be found at Arrow or Avnet but unfortunately there is a 16 week lead time for both.

Thanks,

Dave

Hi,

It doesn’t seem to have any public datasheet, so we really couldn’t make a breakout, as we’d be under NDA for the pin connections to get enough info to make one!

Please correct me if I’m wrong and there is publicly available info!

Cheers,

I bought a Think Outside Stowaway Bluetooth keyboard to hack:

Inside I saw a module I remembered seeing during my searching on the web:

The BT2013F module has the Broadcom Chip and Flash onboard.

Maybe you can setup a relationship with them to sell their modules through your site, or maybe you could put their modules on a board with easier to solder to pads? This one has vias that are chopped in half that are in turn surface mounted to a carrier board.

I wouldn’t mind seeing their [BT3014 module; looks like it would be perfect for some embedded wiimote hacking.](http://www.tecomproduct.com/BT3014.htm)

The BCM2042 is a BGA chip; practically impossible to work with on a small scale. A number of manufacturers have put that chip on a surface-mount module. I have made arrangements with one of them, Blue Packet, to import and resell them.

I have a breakout board, but that’s not really what you want. You really want a board which brings out the keyboard / mouse pins, and has lands for the decoupling caps, bluetooth sync LED, and bluetooth sync pushbutton. I don’t have that board designed yet, but if there’s sufficient interest, I will. Or sparkfun can – not to steal their thunder.

Tecom, like Blue Packet, is very unresponsive. Unless you want to experience the same headaches I’ve already had, you’ll just buy the Blue Packet module from me.](http://www.tecomproduct.com/BT3014.htm)
