Power & Source of Big Ideas

I tried burning ubuntu-25.04-desktop-arm64.iso to an SD card and booting from it but all I got was a black screen.
Is there no mainline support yet?
I think it had something to do with my USB hub and maybe power.
I am trying to install different OSes from an SD card but I keep getting "unknown eMMC" error.
It says it is 0 bytes.
It worked one out of 15 tries.
Is it a power supply issue?
It is 5V, 3A.
Is the download I need to flash the official OpenWRT by setting “autoStart=” in eflasher.conf file on the SD card called rk3568-eflasher-multiple-os-20250701-30g.img.gz?

Regarding the M.2 form factor for SSH on the NanoPi R5S,

Wrong model, it is an R5C (not S).
The R5C form factor is 2230. E-key I think.
It'll be hard to find anything but wifi with the right key.
I use OpenWRT that I build but probably the mediatek 7921au.
The eflasher software doesn't find the eMMC unless an ethernet cable is plugged in.
The wiki mentions USB2LCD. where do I get one?
It worked when I logged in my google account.
I'd rather not be logged in. :-)
Does this help?

PS! The ruler is mm on the right and inches on the left.
I get the error "download quota for this file exceeded at this time, so unable to download at this time". :-(
I didn't know there was only 1 screw, I got mine today. :-)
I don't which part to measure.
It is a plus although that wouldn't matter. :-)
I would take one of the screws you have to a parts store.
I am Canadian so I would go to Canadian Tire.

How do I use one R5C as access point and another as R5C wireless client so I can connect two separate networks together via wireless? Is there another way to do this?


What OS?
Does the amps matter on the power adapter?
I have a spare 5V/3A and I read the specs are 5V/2A.
Is it possible to boot the R5C from USB (or an M2 NVMe drive)?
A boot loader on the eemc that can boot anything would be awesome.
What do I need to add wifi to a non-wifi version?
Do all I need is to buy something like this:

?

An M.2 card, antennas, antenna mounting screws.
Is the hold on the R5C the same size as the baffle?
