Bluetooth MP3 player stereo audio microUSB power for car

Bluetooth XY-BT-Mini player Bluetooth XY-BT-Mini player is a compact device that enables wireless connection to a smartphone using Bluetooth 4.1 technology. The module works excellently in hobby electronics projects, including as an audio extension for ESP8266, ESP32, Arduino, and Raspberry Pi. This mini audio receiver supports music playback in popular formats: WAV, APE, FLAC, and MP3. A wide supply voltage range from 3.7V to 5V allows powering the module with a standard Li-Ion 18650 or 1S Li-Po battery. The device is equipped with a status LED, a microUSB power connector, and a standard 3.5 mm mini-jack audio output. The module makes it easy to upgrade a classic amplifier by adding wireless connectivity. Avoid powering the player from the same source as the amplifier to prevent noise and audio path breakthrough.
