Bluetooth FM MP3 Decoder Board 12V

This 12V car audio decoder board delivers dual-channel 3W output and is engineered for stable operation across automotive voltage fluctuations (10–16V). Dimensions and mounting layout align with common DIN and semi-DIN enclosures. Audio decoding supports MP3, WMA, and WAV files from USB mass storage devices or TF/microSD cards (including FAT32 formatted cards up to 32GB). A digital tube display updates dynamically during FM scan, track change, or Bluetooth pairing. FM radio includes full UK band coverage (87.5–108.0 MHz), manual tuning, and auto-search with station memory. Bluetooth functionality supports A2DP for stereo audio and HFP for hands-free calling — including call answer/end and voice recording. Infrared remote control uses standard NEC protocol and works through light tinted glass or at up to 10m distance. Physical controls consist of four-button directional pad (VOL-, AUTO, COL+, MODE) for intuitive operation. 3.5mm AUX input accepts line-level signals from phones, tablets, or other sources. Recording function saves voice or ambient audio directly to connected USB or TF storage upon MODE button long-press; recordings are playable via long-press of PLAY/PAUSE. Power-off memory retains last-played file and position using 24C02 EEPROM.
