Bluetooth and MSP430 Audio Sink Reference Design

Features

Enables Bluetooth audio (SBC encoding/decoding) with the lowest cost, lowest power MSP430F5229

Enables low-power audio by offloading audio processing from the MCU to the Bluetooth device in the design

This cost-effective, low-end wireless audio solution uses a 4-layer layout and QFN package. The core of this solution is TI's CC2564, which has best-in-class Bluetooth performance (+12dBm output power). The design also uses TI's low-power digital input speaker amplifier (TAS2505) and USB charge management device (BQ24055). Both the CC256x and Bluetopia stacks have Bluetooth subsystem QDIDs, so you only need a list of Bluetooth end products
