Tinker Board Forum

Is anyone else having similar problem?
I bought a Tinker board S, Tinker power supply and a Tinker Fanless aluminum case few weeks ago.
Installed Armbian with kernel 4.4.x.
It doesn't have any problem when it's idle, but when I use it to browse websites sometimes the Tinker board just shutdown completely, when this happens there is not light on the board, but the external 3.5" USB drive I plugged in still has the lights blinking (like the board is still writing something to it.)
This usually happens when I open chromium or when I'm browsing websites.
The use case for the device is for Torrenting and browsing website, And what I can see with "armbianmonitor -m" is that the CPU temperature goes up to 84 degree Celsius when I'm browsing websites but no unexpected shutdown.
What could be the culprit?

Voltage drop due to bad powering. 100%

I thought the official power supply was enough but...

Anyway, I tried to underclock my Tinker Board S, and it's stable for me after 1 day of testing.

methods:
sudo nano /etc/default/cpufrequtils
## Change MAX_SPEED to 16000000 (original value is 19000000)
## CTRL+X, y
sudo /etc/init.d/cpufrequtils restart

And it should show your CPU clock is 1512MHz in "sudo armbianmonitor -m", I haven't tried higher value to see if it's stable, good enough for me.

It's better than just some generic but mUSB is the worst possible way to power a board. It's a RPi likeness trap.
