gounthar Posted April 13, 2020 Author Posted April 13, 2020 The UPS is working as expected, but I still have a problem. If I do a clean shutdown, the board never starts again by itself, because it still has 5V on the micro USB. I guess that if there is no main power source for a while, the charger board will cut the 5V, but it will also take some time before it gives power back to the OrangePi Zero once we plug it in the main power source. Would it be possible to trigger the boot of the OrangePi once we get the main power source back?
Werner Posted April 13, 2020 Posted April 13, 2020 Maybe a small timer relay triggere by mains voltage that opens the 5v to the sbc for a second? 1
gounthar Posted April 13, 2020 Author Posted April 13, 2020 Thanks. There are a few pointers there. I should maybe put the Zero to sleep and not shut it down... so that I can wake it up via GPIO?
