Evaluation Board for Bluetooth 5.0 Audio & BLE/SPP Module

Wireless audio systems and smart home devices are some of the favourites for Makers to start tinkering with Bluetooth. With modules like the Audio & BLE/SPP Pass-Through Module, you can incorporate Bluetooth connectivity and audio playback capabilities into your next DIY project. This Evaluation Board goes a step further as the development platform to help you prototype your applications and utilise the modules audio and Bluetooth capabilities to the best possible.

The Evaluation Board for Audio & BLE/SPP Module includes the module itself integrated into the bigger 45x42mm board. Unlike the standalone module, which is primarily intended for integration into end products, the evaluation board provides additional connectors like pin headers and audio jacks to explore. The comprehensive environment lends well for testing, prototyping, and validating the module's features and capabilities. It provides a convenient platform for testing different configurations, conducting performance analysis, and validating the module's compatibility with other hardware components or systems.

With the Audio & BLE/SPP Pass-Through Module embedded within the Evaluation Board, you can enjoy its many wonderful audio Bluetooth features. The Audio & BLE/SPP Pass-Through Module supports both Bluetooth Low Energy (BLE) and Serial Port Profile (SPP) pass-through functions. This dual-mode Bluetooth enables seamless data transmission between the module and other devices via Bluetooth. The great wireless connectivity and control allows you to make Bluetooth calls and manage audio transmissions. Its UART communication interface simplifies the integration process, making it ideal for hobbyists or professionals.

Support is available for well known audio formats such as MP3, WAV, WMA, FLAC, AAC, and APE, enabling you to play music files stored on U-disk or TF card up to 128GB in size. A wide operating voltage of 3.3V to 5V also opens the door to easily integrate with Arduino boards and other controllers.
