Re: "Power-ON-on-power-fail" functionality?

<t>The device doesn't actually have a standby or "off" mode. It's always on when powered on. To answer your question: yes the raspberry pi will switch on again after a power failure, though there is a chance it'll have corrupted part of the filesystem if it was writing. For like 10 dollars you can b...
