This is DIY Audio MP3. Plays both music and speech from MP3 format. Can read MP3s from an SD card.

This is clear from the picture. It’s not clear how one sentence so messed up.
And it was not in vain that they asked about fan control.
dontknow I did not understand anything from the presented photo description. Some photos of the “box” and “three” words. What is the purpose of this publication about nothing?
Take a word?
I will answer the topic. This is DIY Audio MP3. Plays both music and speech from MP3 format. Can read MP3s from an SD card. And the FM radio receiver is built-in. It is also controlled from the infrared remote control. It also needs ULF (power). I put on the TDA2005R. It is powered from an external source + 12V

And what kind of news is this - "CD cards"?
How is the fan controlled?
