I purchased this kit of Bangood, and yes I know the video says EBAY, I was confused lol
Its a 18W x 2 Audio Amp module with Volumn, Bass and Treble controls. Anyway it went together nicely and worked fine. The only thing I would say is one of the pots was pretty average condition, a but scratchy to turn.
Take a look at the video on You Tube: https://youtu.be/57yKoFy4PxM
If you do a search on Bangood for TDA2030A 2.0 Audio Amplifier Module Board, you should be able to find it.
