FIGURE 1:
General Description:
Stereo module is a fully-certified
Bluetooth® Version 4.1 (BDR/EDR) 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, 29x15x2.5 mm3.
This stereo module built-in Li-Ion charger
and BM23 contain a digital audio interface. It
supports HSP, HFP, SPP, A2DP, and
AVRCP profiles. Both AAC and SBC codecs
are supported for A2DP. Note that the
customer must connect their own external
analog CODEC/DSP/amplifier and MCU for
audio output.
Applications:
Bluetooth sound bar
Bluetooth stereo speaker phone
