Review on HiLetgo DC 8-26V TPA3118 PBTL Mono Digital Audio Amplifier Board π AMP Module 160W for Arduino - Enhance Sound Quality with Powerful Amplification! by Jonathan Abreu
My favorite audio amplifier for small/medium projects
I have used this board for various projects and it has always been reliable. I ran it on 24V, but in most cases 12V is enough. If you're a bit more techy there are several sources on how to improve the board by substituting better capacitors and chokes, but I've never felt the need. The only modification I've come up with is to solder a 4.7uF cap to the "mute" pins to serve as a "de-pop" method to get the pop to eliminate the speaker when power is applied.
