The Power Supply
The TauOUT board provides a DC power jack. You need a single 6.3 – 9.1VDC power supply to power the Raspberry Pi and the TauDAC through the TauOUT board. The power supply should be able to provide at least 1.5A. The DC power jack center pin has a diameter of 2 mm. It is not necessary (and not recommended) to connect an external power supply via USB to the Raspberry Pi.
