Audio & BLE/SPP Pass-Through Module – Bluetooth 5.0

Wireless audio systems and smart home devices are some of the favourites for Makers to start tinkering with Bluetooth. With modules like this Audio & BLE/SPP Pass-Through Module, you can incorporate Bluetooth connectivity and audio playback capabilities into your next DIY project. This module allows for streaming audio wirelessly through transmission and control functions.

Designed with a compact form factor, 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.
