New Product: Near-Field Voice Recognition Full-Duplex Noise Reduction Module – SA628F22Pro

SA6X8 series is our company's 8-channel full-duplex audio module. To meet the needs of professional noise reduction applications, we have launched the SA628F22Pro full-duplex intercom module with built-in noise reduction functionality.

SA628F22Pro is a cost-effective, highly integrated full-duplex wireless data and voice communication module. It offers the same functionality as the SA628F22, with the addition of our self-developed noise reduction module. It enables direct data transmission and reception via a serial port, supporting full-duplex wireless data communication with relay capabilities. The module also supports multi-channel concurrent transmission and reception, Mesh networking, and firmware upgrades via over-the-air (OTA) or serial port.

The module supports up to 80dB noise suppression and delivers optimal performance in near-field voice scenarios (when the speaker is within 10 cm of the microphone). It effectively reduces electronic noise, wind noise, outdoor wave sounds, car horn noise, and sudden interfering sounds.
SA628F22Pro strictly uses lead -free process production and testing, which meets the standards of ROHS and Reach。
