Proview on th Odroid U3+
Debian/Wheezy and Arch Linux
One thing is for sure. HDMI-DVI can be a trouble maker. I was pretty close to use a hammer and to say good bye to the U3. But after I gave another LCD-Monitor a try the problems with HDMI-DVI were gone. Seems to be there are more people with Monitor (settings) problems....
Debian Weezy and a Mega2560.

My first impression of the U3+, Debian/Wheezy in general as PC/Laptop replacement (Proview Development Station).
- Project creation and up start is ok
- GE and the plc editor and compiling, no problem.
- If you are working with many projects:
- Thats up to you
- Lack of I/O compared to the Rpi but tons of possibilities with Arduino, Modbus and Powerlink
- Nice board, if you have luck with your HDMI-DVI monitor....
Arch Linux .....
