BTM-770G
    This is a Bluetooth Class2 (max 4dBm) dual mode module. It is based on the most advanced CSR8670
    chip set and the latest ADK, it can support Bluetooth V4.0 standard. The new RISC MCU core and
    80MIPS Kalimba DSP Co-Processor enable not the existing Bluetooth multi-media function such as echo
    cancellation, noise reduction and stereo audio (A2DP audio) communications but also extended features
    for future. The highly integrated hardware includes high quality stereo DAC, high current (200mA)
    battery charger and, switch regulator. This makes the system design easier and save costs of external
    components. 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. Furthermore, the APTX, AAC, MP3 HIFI audio streaming are also supported.
