This is a Bluetooth class 2 (max. 4dBm) module. It is based on the CSR 8640 ROM version chip set which supports Bluetooth V3.0 standard. The embedded kalimba DSP co-processor supports advanced features such as echo cancellation, noise reduction, and stereo audio (A2DP profile) communications. Advanced user interface design allows multi-point HFP or A2DP connections and secures simple pairing. The integrated stereo DAC provide high quality audio performance with SNR up to 95dB. It can 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. It is the true single chip solution to audio applications. Internal ROM, serial flash and EEPROM enable the flexibilities of the module to meet various kinds of applications.
