And now for something very unusual here: TEA-time!

I've bought on ebay a so-called USB-meter, because I've learned during my last "Reparier-Bar" engagement in January that I need one of these nice buggers.
I've bought it here, it is called a "USB colour display tester":
https://www.ebay.com/itm/303026038488It arrived this week and since I know how curious you lot are, here are the pictures:
(sorry, they are a little bit dark, I really need a better camera than the one from my Xperia Z3)
It comes in a nice box, so the plastic surface of the device is well protected in my tool-box:

This is the top plastic cover removed, not so much to see besides the display:

This is the bottom cover removed. It falled apart in two modules: the controller board and the Bluetooth module

This is the Bluetooth module in detail:

Here we have the controller board with the master brain on it:
The controller itself:

And this is how it looks like when it is operating.
I've connected my wireless mouse (Logitech MX anywhere 2) to it (charging mode):
screen 1:
This is the main screen which displays voltage and current drawn,
together with the temperature, charge, internal resistance of the target, energy and power

screen 2:
not sure about this one. It shows again voltage and current but additionally some USB differential(?) voltages
and a Mode thing

screen 3:
This screen shows the charge and energy and the uptime:

screen 4:
not sure about this one, too. Some "Port" information:

screen 5:
This is a nice y/t display which shows voltage and current over time. I like this one.

Hope you enjoyed this little teardown.
