Description:

KCX-BT-EMITTER module is a Bluetooth audio transmitter and receiver module that integrates computer USB sound card to Bluetooth transmission and line audio input and launch. It adopts Bluetooth 5.3 technology to greatly ensure the quality and stability of audio transmission.
This product can be used for most of the products. Bluetooth transmitter function for desktop computers, notebook computers, TVs, projectors, game consoles, IPOD, CD players, MP3s, etc., to transmit audio signals to Bluetooth audio receivers such as Bluetooth headsets or Bluetooth speakers to form a wireless audio transmission system. 

This module is a Bluetooth host device (equivalent to mobile phone Bluetooth), which can be connected to a Bluetooth audio receiver (such as Bluetooth speaker, Bluetooth headset, or any Bluetooth audio receiver module board in the store) to form a wireless audio transmission system.
The audio signal is input from the module, and the audio signal transmitted by the module can be received on the Bluetooth audio receiving device that establishes a connection with the module.
