Audio & BLE/SPP Pass-through Module - Bluetooth 5.0

The Audio & BLE/SPP Pass-through Module is a compact Bluetooth 5.0 dual-mode board designed for simultaneous audio streaming and wireless data transmission. It is an ideal solution for makers, students, and embedded developers needing media playback and serial communication in a single module.

Dual-mode Bluetooth 5.0 operation

The module features dual-mode Bluetooth 5.0 capabilities, running audio playback and data transmission at the same time. This simplifies embedded development by combining wireless audio streaming and serial control on one board.

BLE and SPP data pass-through

Equipped with BLE and SPP pass-through functions, the board allows seamless wireless serial communication. It supports clear and simple UART control commands for straightforward integration with microcontrollers.

Broad audio format and storage support

The module decodes MP3, WAV, WMA, FLAC, AAC, and APE audio formats from TF cards or U-disks up to 128GB. It also supports Bluetooth audio transmission and Bluetooth call control functions.

Compact footprint and low power draw

Measuring only 23 by 15.5 mm, the module operates from a 3.3V to 5V supply with a working current of 20mA. It is rated to operate across temperatures from -40°C to 80°C and humidity levels from 5% to 95% RH.
