Up to the RPI4, I was pretty sure there wasn't PD, just 5V and it drew what it drew, and you hoped that the supply was big enough. It seems the RPI5 will use PD if given a capable supply. Looks like 5V 5A, and it won't negotitate higher voltages. There's an official supply that does PD https://www.newark.com/raspberry-pi/sc1153/power-supply-usb-c-5-1v-5a-white/dp/82AK3955 and the output spec is 5A at 5.1V, 3A at 9V, 2.25A at 12V, 1.8A at 15V looks like a TUV seal I find Jim's way of using this interesting, but my approach is totally different. First, when I'm using a Pi, it's because I want a low power computer that I can leave on all the time, or can place in a different physical location I don't particularly want to do things on a Pi instead of a desktop. And then I want it to be reliable. That leads me to plug a power supply into a UPS, or to use POE (from a POE switch which is plugged into a UPS). For RPI3, I found a POE ejector that splits the POE ethernet cable into ethernet only and a micro USB. _______________________________________________ Nut-upsuser mailing list [email protected] https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
