I need to setup another cheap zone in my house, so looking to get a RPi paired up with an IQAudio Digiamp+ and my QAcoustic 3020 speakers. Just before I click “buy” on all the components, what do people generally do for an off switch if running headless? I saw a good article on hear about someone that made a good RPi + Digiamp+ setup, but have just spent about an hour searching for it without luck!
There should be a way to fit a switch like any regular computer board. The machine should then shut down gracefully. Does anyone know specifically if this is not the case?
When connected to an IQAudio DigiAmp+ the Pi gets its power from the HAT (which is fed via a 19 volt DV power supply, as it also has a speaker amp) so the inline USB option wouldn’t work I don’t think. I’m happy just switch it off at the wall when required, but believe that often leads to corruption of the MicroSD card?
