Hello,

I would like to request a tear down of this product:
http://www.sureelectronics.net/goods.php?id=2698

I made something a bit similar and I wonder how my design differs from this.

Thanks in advance!

Edit: I used a small board with an PT2313 + AVR and a Cubieboard 2. I have some boards with PT2313 left over, let me know if you are interested.

Here is a datasheet/document for the slightly lower end one without the whizzbang features.

aliexpress sellers often include an internal shot, but I didn't see any which were identical model

Thank you for the effort guys, but I didn't see what I was looking for yet.

Hello happylex,

If you're still intrested in the subject, I just both one of these amps and opened it to see what's inside. I have pictures but they are too large to attach all in this post.
I can tell you it uses:
PIC16F690 microprocessor
PT2348-X audio 4.1 sound processor with subwoofer out
TTK BTM-68D V4 bluetooth module
WM8804G S/PDIF Transceiver and CS4334-KS 24-Bit, 96 kHz Stereo D/A Converter for the S/PDIF input
And some 8-pin SMD chips that seem like OPAmps.

You can leave me a PM with an email address if you want me to send you all the pictures.

Hope you'll find this useful.

Regards,

Florin
