So I’m new to volumio and I currently have a Raspberry Pi 3 Model B, and when i boot it up after flashing it, i’m prompted with Under-voltage detected! (0x00050005). I can still input the login, but when i press enter to get to the password line, I can’t input anything.
Just use a browser or the app on your phone to manage it and finish the setup.
But it sounds like you may need a better powewr supply for it.
