Dfplayer Mini MP3 Player Module for Arduino Voice Module for Arduino DIY DFPlayer Mini Voice Decode Board Supporting TF Card U-Disk IO/Serial Port/AD for arduino DIY Kit

Great MP3 player for my application of sound fx on a model railroad. Very good sound produced on 8 ohm 4 watt speakers. Works well on the 3 ohm speakers I had from an old home theater system also. I was surprised at how loud the volume was at the highest setting. I had to set my volume at mid range. Easy to understand instructions and very easy to incorporate into any Arduino project.

This is junk. The unit is dead on arrival and is covered with corrosion right out of the package. I am posting this about an hour after this was delivered to show what this company packages and ships. The package was factory sealed when delivered so this is what you get not what is pictured or described. The photos show the corroded connections and sweat from handling this at the factory. With 8 dead solder connections it's obvious why this product is not usable right out of the package.

I used a couple of these with Arduino projects. It's got a memory card slot so you can load music or sentences, or sounds. In your Arduino program you can play individual tracks. It works nice and is reasonably priced. Try it.

Worked by itself but was not able to communicate with the Arduino via serial communication (tested all possible variables)
