The BM64 stereo audio module is a fully-certified Bluetooth 5 module for designers who want to add Bluetooth wireless audio and voice applications to their products.

This Bluetooth SIG certified module provides a complete wireless solution with Bluetooth stack, integrated antenna, and worldwide radio certifications in a compact surface mount package.  This stereo module has integrated Li-Ion charger and I2S digital audio interface.  It supports HSP, HFP, SPP, A2DP (Sink), and AVRCP profiles and AAC and SBC decoding.

Bluetooth Low Energy supports standard Generic Access Service, Device Information Service and a proprietary service for data communication.

Microchip’s Wireless Concert Technology (WCT) for speakers uses Multi-Speaker (MSPK) firmware to stream A2DP music to multiple speakers from one audio source, such as a smartphone. This unique solution delivers tight synchronization among the speakers to deliver uninterrupted, distributed audio. Use personal sharing groups to easily pair speakers and assign master and slave roles via the Microchip Bluetooth Audio (MBA) Mobile app.
