Shenzhen Youanhong Technology Co., Ltd.

It is a high-performance
/embedded
network audio module, using
br/ +
architecture, which can receive network audio data streams and convert them into audio simulations signal output. It can also sample local

input or

input and send it to the network for other network audio modules to receive and play. Provides voice-level two-way audio data transmission to facilitate the construction of network voice intercom systems.
The module also provides two sets of power amplifier (*) control interfaces, with mute output, working signal output, relay output and switch input, which can easily control external high-power amplifiers. Provide

a user serial interface for receiving user commands and feedback module information,

a virtual serial port to facilitate the expansion of user applications,

Expansion serial interface, which can be connected to serial devices such as serial cameras.

and
dual-processor architecture.
The processor is responsible for data transmission and parsing and execution of user commands. As well as the control of the power amplifier interface, it is responsible for the encoding, decoding and output of voice data. Through the network transformer,

can be directly connected to Ethernet.
