YL2020 20W+20W D Class 12V-24V Mini Digital Power Amplifier Module is simple and mini size class D power amplifier but it has a remarkable audio power output via its dual stereo channel of 20W per channel
Schematic and Pin Description:
As you can see in the schematic it is a small PCB, easy to install, with marked terminals and convenient for soldering. You just need to solder everything where it belongs.
If you do not use MUTE, connect FAULT and MUTE together – it will mute the amplifier in case of errors.
To enable MUTE, it must be connected to the positive supply voltage VCC (Smaller enough, but it is the easiest way).
The SD input is! SHUTDOWN, no need to plugin, and don’t use it as a mute either, as using it will make your speakers pound.
