The BlueTunes2 development kit contains everything for rapid evaluation and development of Bluetooth stereo and mono
audio applications. It is based on CSR’s latest generation single chip Bluetooth audio solution: BlueCore5-Multimedia. The
BC5-MM chip offers best in class performance with an integrated 64 MIPS DSP, audio codec, SMPS, battery charger and
Bluetooth radio, thereby enabling advanced and ultra-compact stereo and mono headset solutions with less than 50 external
components. Users can start evaluating straight away as the BlueTunes2 kit comes pre-loaded with stereo headset
application software, including CVC echo and noise cancellation.
Along with CSR’s BlueLab 3.6 software development suite and the CSR headset configurator tools (available separately) the

BlueTunes2 audio development kit contents
BC5-MM Stereo headset application board
Analogue Audio Adaptor board
This board features the latest CSR BlueCore5-Multimedia
Bluetooth audio solution. It interfaces with stereo
headphones and microphones and has flexible LED and
push-button assignments. Battery current measurements
can be carried out with a standard multimeter, and a PIO
header allows for connection of further application
hardware, such as displays.
The analogue audio adaptor board has a 3.5mm jack input
for connection with analogue audio sources such as MP3
players or radios. This board will stream stereo audio from
these sources over Bluetooth to A2DP Bluetooth audio
sinks, such as the BC5-MM Stereo headset application
board.
VOIP & Music USB dongles
Headset, cables and quick-start guide
Included in the kit are a pair of high-quality stereo
headphones with microphones as well as a quick-start
guide, cables and programming hardware.
