SA316 : High Fidelity Wireless Audio Module

NiceRF launched a new low-latency, long-distance, high-sampling rate, high-fidelity wireless audio module SA316. SA316 series products are divided into transmitter module SA316-TX and receiver module SA316-RX. This series of solutions adopts wireless high-quality voice transmission chip to design, it can support external PCM / IIS dual-mode digital audio interface, and the module is The customer provides a standardized serial interface. The user can quickly and easily set the module's transceiver frequency, sound size, microphone gain and other parameters through the serial port command, which is widely used in occasions that require relatively high sound quality.
