IntroductionStationPi Pro is particularly designed for integrating RaspberryPi based audio applications. It can optimize the digital audio projects, such as transports or DACs, to make them more organized and well finished. The whole audio performance can also be improved as a consequence of a lower EMI noise.StationPi Pro is a fully assembles/finished product. Highlighted Features Separate RaspberryPi and audio HATs into two stacks configuration, Independent power supplies for both RPi and audio stacks. Double ground plates to shield the RaspberryPi EMI noise. Easy and organized to integrate a whole audio project. Audio HATs can be installed in two different originations to meet the requirements of applications. Comes with a full set of screws and standoffs. Great to build DAC or digital transport projects. KIT includes A whole piece of assembled StationPi Pro PCB and the daughter board PCB Two shield plates with spacer bits 6 x 6mm M3 standoffs 6 x M3 screws 6 x M3 nuts 4 x 11mmm M2.5 standoffs (to mount the Raspberry Pi to the daughter board) 8 x 13mmm M2.5 standoffs 5x12mmm M2.5 standoffs 13 x M2.5 screws 13 x M2.5 nuts 6 x 2.54mm jumpers In case you need a USB digital interface: Amanero Combo384 is highly recommended User's manual Documents https://github.com/iancanada/DocumentDownload/tree/master/Adapters/StationPiPro
