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.
