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.
