Introduction
This module is with CSR BlueCore5-Multimedia External solution. It is a single-chip radio and
baseband IC for Bluetooth 2.4GHz systems. When used with the CSR Bluetooth stack, it provides a fully
compliant Bluetooth v2.1 + EDR specification system for data and voice.
BlueCore5-Multimedia External contains the Kalimba DSP co-processor with double the MIPS of
BlueCore3-Multimedia External, supporting enhanced audio applications.
