This is a Bluetooth Class2 (max 4dBm) module. It is based on CSR 8640 ROM version chip set which supports Bluetooth V4.0 standard. The Embedded Kalimba DSP Co-Processor supports the advanced features such as echocancellation, noise reduction, and stereo audio (A2DP profile) communications. Advanced user interface design allows multipoint HFP or A2DP connections and secures simple pairing. The integrated stereo DAC provide high quality audio performance with SNR up to 93dB. And the on chip Switched-Mode Regulator and Li-ion battery charger eliminate the needs of external components and costs. The true single chip solution for audio applications. Internal ROM and EEPROM enable the flexibilities of the module to meet various kinds of applications.
