Audio playback is being incorporated into a myriad of different devices today, with Bluetooth and USB streaming quickly replacing the 3.5mm line out jack as the preferred connection method. This hardware kit fits the need of an engineer being tasked with developing solutions for things such as Bluetooth/USB streaming portable speakers, smartphone docking stations, or automotive docks. For customers looking at non-audio based solutions, due to its modularity accepting other Microchip Plug In Modules, this kit can also be used for customers looking to develop small user interfaces, USB to Bluetooth adapters, or simple talking applications.
