Running OpenBSD on Raspberry Pi Zero 2 W

This is incredible! I have a zero 2W somewhere, though I put it into
a GPI case. The drawback with the GPI case is it will not boot with
batteries, because it's really made for the zero 1W, so it's bonded
to the USB power cable. I'm gonna try putting this on! Thank you in
advance.
The GPI case uses a LCD display (It's the gameboy) do you know any BSD
drivers for this?

I have another use for this RPI Zero 2W, I want to make it a remote
power switch for 5x USB and 3x 220V AC. I once purchased this (for
another project and I think I'll reuse this):

My question then is... would I have any problems with the GPIO controls
with OpenBSD on RPI zero 2W?
Otherwise I'll have to make it another OS.

PS: I'll probably do this next week I have a need for different
hardware in my 9U rackmount cabinet. And one particular one needs
powercycles (and possibly console) as well. It's the mango pi, which is
currently in panic mode most likely or it's hung up, I was building
ports on it and the 100 Mbit connection went down.

I'm still playing with this kind of stuff. Good luck on your
journey, but
it will be a rough ride. You already mentioned some issues.
I have/had a pair of Raspberry 3B and also a pair of Pine64 SBCs,
running
OpenBSD 7.x and CARP failover for experimental things. Working,
but not as
reliable as I would like.
You seem to aim at even smaller boards like that, and newer ones
should match
the specs of Raspi3B or Pine64. However:
- there is no fine "sysupgrade" for these platforms, so you need
to reinstall
every time
- which means fiddling with non-OpenBSD "uboot" and EFI
definition files
- consider creating a network boot infrastructure
- these devices are very sensitive to power voltage
instabilities, triggering
spontaneous reboots. You may want to run them from stable USB
power source
- I doubt this can be reasonably battery-powered, over longer
time periods
- storage like SD-card or eMMS draw extra power during operation,
writes may
be unreliable during voltage drops
- storage like SD-card or eMMS will wear out and die hard, sooner
or later
- Wifi hardware may not be supported
- RS232 serial usually provided (and working) by bus pinout, but
you need to
add a FTDI232 or CH340 adapter
That said, I'd like to hear about it if you find interesting
hardware :)
