Unfortunately yes, it's 3B+.

On raspbian I never got lightning bolt. And at some point, prior to
raspbian I have used NetBSD on it (7 or 8 not recollecting) with no
lightning bolt problem. (It was there, but was solved by copying firmware
files.)

BTW the firmware files for RPI0-3 are still changing upstream. See [4] in
my last mail. Some timestamps are of last 2 days, too. You might want to
try the latest ones.

I am just in the middle of re-flashing with NetBSD 9.1 armv7 image, the
official release. One where I faced issue was a daily build of 10 Nov or
so - not much difference I suppose, but still...

Thinking about getting 4 - 8GB, whenever I get next!
