I just got a Pi 5 yesterday. Currently I'm not planning on replacing the Pi 4 in my sBitx DE.
Off topic: have you tried booting your Pi 5 from an external USB drive?? I have a USB3 enclosure with an NvME SSD. You can use the Raspberry Pi Imager software to create a bootable USB drive. I tried booting my Pi 5 it and while it boots and runs fine, if I try and update the software, I get a "drive was removed without ejecting error" and have to do a hard shutdown.? The failure is repeatable. The same NvME drive works fine on my Pi 4's (one in the sBitx) and my Pi 400. To eliminate the possibility that the drive was drawing too much current, I connected it to a powered USB3 hub - same failure.? I'm trying to figure out if the problem is with the Pi 5 in general or if my board is defective while I can still return it.
