Hello, I'm a french IT teacher specialised in linux,
This next year of school (September 2018 - June 2019) my students will build some projects, these projects are 70% of their final grade after 3 years of school.
I have 35 students divided into groups of 5 (so 7 groups). For exemple one of the groups will build a solar cluster. And one student of this group suggested that we use orangepi's because he has already used them and he said they are inexpensive comparing to the raspberrys. So I said that I will test them, I bought myself an OrangePi zero of ebay with its case and the USB board that goes into it, I use it with armbian and I have to say that it's pretty good, I had some issues with the first wifi connection but solved it with a simple google search, I'm asking you to send me 8 orange pi zero plus 2 so they can benefit from a decent setup that would be able to run on usb power and wifi once configured with their projects.
If you need more information, please contact me in private.
If you accept, but you think that another board would be more useful please send me the more adapted one.
Respectfully, thanks
