1. Overview

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.
