Overview TheSA316seriesproductsaredividedintotransmittermodulesSA316S-TX,SA316F30,andreceiver 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 insituationsthatrequirehighsoundquality. 2.
