Bluetooth Pixel Tester w/12v PSU

This thing is awesome!

Great pixel tester. Easy setup. App QR code on the device. The picture is a custom 840 pixel screen.

this is a great tool, works just as it should. I like that I can set it to count the pixels for me too.

This is awesome! So much easier than my old way of using a power supply and cheap controller. This frees up a power supply! Really easy to use.
