i’m starting a volumio project with :
Raspberry pi (3b+ or 4 i have both and make testing)
This usb Dac
An oled screen : 2.42" OLED Display ssd1309 128x64
A momentary push button (12V white light circle)
Two vu meter here (12V needed)
i’m searching for a low level noise power supply for the raspberry and his Dac attached, and i need 12V for the vu meter and the power button.
wich power supply i needed ?
i would like use this product but i’m unable to find the good Toroidal transformer…
I have planned to power up the raspberry with the gpio (GPIO2-3),
how can i drive the 12V on with the raspberry power on ?
many thanks !!!
