Product Description

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. Further more, advanced stereo audio codec such as APTX and AAC are allowable. That is, to provide high quality audio with low latency time.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 upgrade.

The powerful and flexible design allows the module to support HSP/HFP/A2DP/AVRCP SPP, PBAP,…all kinds of Bluetooth profiles.
