This high-fidelity wireless stereo audio transceiver module integrates both wireless stereo audio transmission and reception. To stable wireless transmission, this module utilizes an adaptive frequency hopping algorithm. When it detects channel congestion, it automatically switches to a relatively free channel to continue communication. To address signal confusion, this module uses an 8-bit address code to distinguish between receivers and transmitters. Connections are established only when the address code of the receiving module matches that of the transmitting module; otherwise, no connection is established. This module utilizes a proprietary 2.4G wireless communication protocol and codec algorithm, employing a "broadcast" transmission mode and supporting multiple receivers (., an unlimited number of receivers can simultaneously receive signals within the transmitter's coverage area). This module is widely used in applications requiring wireless audio transmission and DIY wireless speaker modifications.
