Long-distance, high-quality, low-latency, high-fidelity—SA316 wireless audio module takes you on a journey to explore new audio experiences

By sdga:

The SA316 series products are divided into transmitter modules SA316S-TX, SA316F30, and receiver module SA316-RX. This series uses a wireless high-quality voice transmission chip for its design. It can support external PCM / IIS dual-mode digital audio interfaces, and provides customers with a standardized serial interface. Users can quickly and easily set the module's transceiver frequency, volume, microphone gain, and other parameters through serial port commands, which is widely used in situations that require high sound quality.

The SA316 series wireless audio modules include two models: SA316F30-TX and SA316S-TX. The former, as the transmitter module, is suitable for scenarios with higher distance transmission requirements, while the latter, as the receiver module, is more suitable for shorter distance transmission needs.
