G-NiceRF SA628F30-U

SA628F30 is a cost-effective, highly integrated full-duplex wireless data and voice communication module. Users can read and configure the module's internal parameters and control its transceiver functions via a USB serial port paired with a user-friendly PC interface. Through the serial port, data transmission and reception can be performed directly, enabling full-duplex wireless data transfer with relay support. The SA628F30 module integrates a high-speed MCU, high-performance RF chip, and power amplifier. During operation, users only need to connect an external power supply and speaker to easily achieve long-range wireless transmission of digital voice — simple and efficient. The module employs wideband spread-spectrum technology, featuring low power consumption, long transmission range, and flexible frequency adjustment. Users can implement wireless voice signal transmission via either an I2S digital audio interface or an analog audio interface. The SA628F30 supports multi-channel concurrent reception and multi-level relay long-distance transmission, as well as OTA or serial port firmware upgrades. The SA628F30 is manufactured and tested strictly using lead-free processes, compliant with RoHS and REACH standards.
