Banana Pi M64 http://www.banana-pi.org/m64.html
the default ubuntu os is crap, requesting for an armbian build
Allwinner a64
2GB RAM
not sure i would work but try and cross your finger:
sudo dpkg --add-architecture armhf
sudo apt-get update
sync
sudo apt-get install libc6:armhf
sync
sudo reboot
* update: you may need some other lib, just use package:armf when install
* Update2: you may need also this:
sudo apt-get install libstdc++6:armhf
if some other 32 lib is required to run teamviewer, try: file teamviewer (the binary) to find more about.
