This is similar to what I used.

TPA3116 Amplifier Audio Board 5.1 Channel Digital Power Amplifier Board 50 A7L0 4894803344630 | eBay

Actually I used the version with 2 3300uF caps, not one as on this board,

The 2 cap version has an error in the silk screen on the + MS - terminals. They have the characters upside down. It
SHOULD be - SW +. Just verify the phase is correct. Otherwise I'm very happy with it. I use 19V 180 Watt laptop supply
for power which limits to around 20 Watts into 8 ohms. 24V will get 25-30 Watts.
