Extremely cheap MP3 player (verified)

Overview

Please be informed that there is a personal QR code on the PCB of my project. If you mind, please delete it.
The size of the proof is 3.5x3.5x2cm. It has
the function of music playback, supports C port reading and writing, USB sound card
master control Jerry AB20CKD40H, and was disassembled from an MP3 I picked up. There is no external speaker. It
took me a week
to verify that the function is normal.
