Hello,
I've received my OPi Zero a few days ago. I've installed Armbian 3.4.113 (Debian Jessie) on it. Everything seems to be working fine.
However, I'm worried by the temperature of the thing. With just the default installation and no extra installed, I get the following:
root@orangepizero:/home/sysadmin# armbianmonitor -m
Stop monitoring using [ctrl]-[c]
