Excellent player for a pittance. Reads from a flash drive and memory card. You can listen to music through headphones or by connecting an amplifier. There are terminals for an external speaker. The volume can be adjusted by pressing the Repeat button, adjusting the press time experimentally. The Mode button is Stop. Powered via a charging cable. Runs on an external battery for less than a minute before shutting off. There is no connection diagram for other boards or a display.
Excellent board, mp3 player! Thank you.
Fast shipping, delivered undamaged. Very good product.
I liked the product, I'll buy more.
