I am using a PCM5102 DAC with additional buttons connected to GPIO. The button that is highlighted is connected to GPIO3, when you click on it, the device turns on and off. In standby mode consumes 0.3 A
Since all this is connected to the music center, when the signal from the DAC disappears, the music center falls asleep after a while
For the next project, I have already prepared a more powerful power supply with a shutdown delay relay and a separate button for GPIO3. In the new project, I will use a higher-quality screen and a higher-class DAC.
a set of components for the power supply
