Comimark INA333 Precision Instrumentation Amplifier Review

This amplifier falls short on quality. While it may seem like it would be a good addition to your setup, it actually causes more problems than it solves .It's difficult to install and doesn't live up to the expectations set by the manufacturer..

This tiny amplifier is a game changer for anyone looking for reliable and precise sound output from their single board computer. As my tests showed it greatly improved the audio quality ON my Raspberry Pi.The compact design makes it easy to mount and the low noise feature ensures distortion-free playback. The only downside is that it's a bit pricier compared to other similar products, but the quality is well worth the investment. Overall, i highly recommend this product for any audio-focused…

There is no documentation on this, none at all. Had to create my own documentation to connect this properly - see attachment. It probably would have worked much better if the assembler removed all the loose solder balls. At least it works. It's a shame they complicate such an easy to use item with lack of documentation and sloppy craftsmanship.
