BM20/23 Bluetooth® Stereo Audio Module Introduction
The BM20/23 stereo audio module is a Bluetooth v5.0 (BDR/EDR) audio module for designers to add 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 contains a built-in Li-Ion charger and a digital audio interface (BM23). It supports HSP, HFP, SPP, A2DP, and AVRCP profiles. Both AAC and SBC Codecs are supported for A2DP.
Note: 
The customers must connect their own external analog Codec/DSP/amplifier and MCU for audio output.
