MP3 Speakers

For an upcoming installation, we need a few speakers hanging on the walls playing back sound files in a loop. I found the DFPlayer Mini to work well. It's a small and cheap board that can play sound files from an SD card and it has a built-in 3W amplifier. With a decent 5V power bank (here 4400mAh) it can run for ~4 days continuously.
