12V Bluetooth MP3 Audio Decoder Supports USB MicroSD With Remote Control

12V Bluetooth MP3 Audio Decoder Supports USB MicroSD With Remote ControlThis versatile 12V Bluetooth MP3 Audio Decoder board is designed to modernize legacy audio systems by adding wireless streaming, USB playback, and FM radio functionality. Furthermore, it supports both USB flash drives and MicroSD (TF) cards for direct local playback of digital music files. Consequently, users can easily enjoy their favorite tracks without needing a constant smartphone connection. Therefore, it is an ideal choice for upgrading vintage car stereos, active speakers, or DIY boomboxes. However, users must ensure a stable 12V DC power supply to prevent operational resets or audio distortion. Specifically, the included infrared remote control allows for effortless track selection, volume adjustment, and mode switching from a distance. Moreover, the integrated LED display and onboard buttons provide straightforward manual control over all media functions.
