High-Power Full-Duplex Audio Module: Efficient Heat Dissipation for Diverse Communication Environments

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.

 Core Features: Full-Duplex and Powerful Mesh Networking Performance

8-Channel Full-Duplex Data and Voice Communication
The SA628F39 module supports 8-channel full-duplex data and voice communication, enabling real-time voice calls and data transmission between multiple devices. The full-duplex mode allows users to send and receive data simultaneously. Additionally, the module is equipped with an echo cancellation function to ensure clear voice communication and avoid interference from echoes.

Mesh Self-Networking and Multi-Channel Concurrent Communication
The SA628F39 supports Mesh networking, allowing devices to automatically form a network and dynamically route signals. It also supports 8-channel full-duplex multi-channel concurrent communication, enabling low-latency, high-efficiency, and stable data and voice transmission.

Multiple Security Protection Mechanisms
The module integrates multiple security protection measures, including reverse polarity protection, overcurrent and overvoltage protection, and anti-crash protection, effectively handling sudden voltage fluctuations and device malfunctions, thereby enhancing the stability and lifespan of the device.

The SA628F39 full-duplex audio transmission module also features an ESD  protection chip, which efficiently absorbs and releases static energy, preventing damage to the module's internal circuits caused by electrostatic discharge.

Efficient Heat Dissipation Design: No Additional Heatsink Required

The SA628F39 module features an efficient heat dissipation design that optimizes internal heat distribution. Combined with a high thermal conductivity heat dissipation base, it rapidly transfers the heat generated during operation to the exterior, significantly improving heat dissipation efficiency. This ensures stable and reliable performance even during continuous high-power operation, prolonging the device's lifespan and making it suitable for applications requiring long operating hours.

When 8 users are communicating simultaneously, the SA628F39 module operates without the need for an additional heatsink. This design not only guarantees the stability of high-power operation but also reduces the size and weight of the device, making it more portable.
