ABOUT US

SA628F30 is an embedded wireless digital and audio dual-function full-duplex transmission module. Users can not only wirelessly transmit data through the serial port but also wirelessly transmit voice signals through the I2S digital audio or analog audio interface.

The SA316 series products are divided into transmitter modules SA316S-TX, SA316F30, and receiver module SA316-RX.

SA316 is an audio transmission module developed by NiceRF for long-distance transmission. With an audio sampling rate of 48K and a transmission distance of up to 200 meters, it meets a wide range of user needs. To further extend the transmission distance, NiceRF has introduced the SA316F30. This enhanced version maintains the same 48K sampling rate and -96dBm sensitivity, but significantly extends the transmission distance to 1500 meters.

This set of audio transceiver modules includes the SA356-TX, a 5W transmission module, which can be paired with the SA326-RX receiver module. The SA356-TX is an amplified 5W version of the SA316-TX application board. It starts working as soon as it is powered on, and users can directly set the module's frequency, volume, and other parameters using PC software, significantly simplifying the development process. This product is widely used in scenarios requiring high audio quality.

Full-duplex audio modules can provide various application solutions for communication in subways and tunnels, ensuring efficient and clear communication while addressing the challenges of these unique environments.
