the intercom audio module is a newly developed network audio module that integrates all application functions, focusing on the development of two-way network intercom broadcasting. It is a high-performance/network audio module using + architecture. Compared with or audio module, this new network audio module provides all (necessary and extended) functional interfaces, which is equivalent to a set of mini development boards. Users can test and develop their own without any external expansion circuit support. audio products. The software is used to configure network parameters such as module addresses to realize the development of network audio broadcasting and network voice intercom systems. (,
