I have built a few amps around the 7492, 3116 etc with standard RCA inputs, now I would like to try a project with bluetooth input.
Can anybody recommend a good board, maybe based on 7492 or similar as I only need about 20W (50W max).
Thanks

This board works fine. Just notice that it will not go down to 12v but only operates between 18-24v.
An externally hosted image should be here but it was not working when we last tested it.
Hey thanks magnus, i was hoping to keep my amps at 12v for common pwr sup use, but i'll check it out.
Looks like it is bluetooth only, I think I have seen some boards that are dual input, RCA + bluetooth. Think I would like the RCA input as well.
have you considered an add-on board?
i haven't used this product, but Sure has a board that runs on 12v :

I have just received this same board, but it generates a heck of a lot of noise. Am I doing this right? board is sitting on a piece of cardboard, its not mounted to anything. If I set the phone 2" away from the circuit board, the noise abates very slightly. I'm assuming its noise generated in the bluetooth receiver portion of the amplifier.
Are you seeing this at all? Any quiet passages in the music is just terrible to listen to.

This board works great, it's bluetooth only, no inputs. I super glued the board to the outside of one of a pair of Realistic minimus-7 speaker. Very quite, it's BT 4, 12v and inexpensive. perfect for a BT tablet, my granddaughter will get it, once I have finished enjoying it.

I was about to post a new topic but this seem like a good thread to piggyback on. I was looking at the TDA7492 BT board listed by radiosmuck above but saw a youtube review claiming that this TPA3116 based board was better.
Any thoughts or comparisons? They look and cost almost exactly the same.

Check out the 3116 postings, it seems the board needs modifying to sound good, the thread goes on forever.
