SA628F39 8W High Power Full-Duplex Audio Transmission Module
SA628F39 is an 8W high-power, full-duplex wireless data and Audio module. Users can read and configure the module's internal parameters through a USB serial interface, along with a user-friendly PC interface, and control its transmission and reception functions. Data transmission and reception can be directly performed through the serial port, enabling full-duplex wireless data communication with mesh functionality.
SA628F39 features multiple safety mechanisms, including reverse polarity protection, overcurrent and overvoltage protection, and anti-freeze protection, ensuring stable operation in various complex environments. Users only need to connect the power supply, speaker, and microphone to easily achieve remote wireless digital voice transmission. The module is simple to operate and quick to deploy.
SA628F39 supports multi-channel concurrent reception and Mesh self-organizing network functionality. It also supports over-the-air (OTA) upgrades or serial upgrades.
SA628F39 module is designed with efficient heat dissipation and a thermally conductive base to ensure stability and reliability during high-power operation.
SA628F39 is manufactured and tested using lead-free processes and complies with RoHS and Reach standards.

In high-power module design, heat dissipation is a critical factor in ensuring stable operation and extending the lifespan of the device. The SA628F39 module features an efficient heat dissipation structure with optimized internal heat distribution. Coupled with a high thermal conductivity base design, it quickly transfers the heat generated inside the module to external cooling devices, effectively improving heat dissipation efficiency and ensuring the module's stability and reliability during continuous high-power operation.
module has high power, and using a standard antenna may not yield optimal performance. NiceRF recommends the following two antennas
1.BLG-UHF40
2.SW-UHF390
