This Bluetooth module is miniature in size and has a JST wire. Any portable speaker uses this board extensively. DC 3.7V-5V is the board's operating voltage. This board has the capacity to drive a speaker so that you can directly connect to it. Bluetooth, FM, MP3, a micro B-type USB port, a microchip slot, an auxiliary cable jack, a USB output port, and the most important built-in sound sensor or mic are all present. High-quality sound and bass are provided by the microchip technology on this board. There is a voltage regulator in it. This circuit board is an all-in-one device that includes Bluetooth, an FM radio, an MP3 player, and a sound sensor for recording.
