This is a Bluetooth Class2 (max 4dBm) module with on board antenna.
The on board antenna eliminate the need of matching circuit on the
main board and therefore save the costs of production test. It is
based on CSR Bluecore 5 (BC5)-MM chip set. It can support Bluetooth
V2.1+EDR system. The Embedded Kalimba DSP Co-Processor supports the
advanced features such as echo cancellation, noise reduction and
stereo audio (A2DP profile) communications. Thanks to the 16M bits
program flash memory, the module can be integrated with fruit of
Bluetooth profiles stack to meet various kinds of application. The
integrated stereo DAC provide high quality audio performance with
SNR up to 95dB.Support digital audio bus such as PCM, I2S or SPDIF. And the on chip Switched-Mode Regulator and Li-ion
battery charger eliminate the needs of external components and
costs. The host Interfaces include USB and UART, that are
programmable for data communication, module control or firmware
The powerful and flexible design allows the module to support
HSP/HFP/A2DP/AVRCP SPP, PBAP,…all kinds of Bluetooth profiles.
