In both cases, you do not need to plug in to the microUSB port in the Raspberry Pi. The DAC powers the Pi as well.
- Power by single microUSB (Shared power with Raspberry Pi)
- Individually Powered
NanoSound DAC only
Assemble the included screws as shown below
NanoSound DAC & NanoSound AMP^2
- Mount Amp^2 to the bottom of DAC. Do not over tighten the screws so that the 2 boards are roughly parallel
- Mount them onto the Raspberry Pi as shown. The speaker terminals will cover the Raspberry Pis microUSB power. This is not a problem since the DAC will power the Raspberry Pi as well.
