Considering how I have absolutely no idea what those things are, here is what they are according to their manufacturer over at Asus:
Tinker Board is a Single Board Computer (SBC) in an ultra-small form factor that offers class-leading performance while leveraging outstanding mechanical compatibility. The Tinker Board offers makers, IoT enthusiasts, hobbyists, PC DIY enthusiasts and others a reliable and extremely capable platform for building and tinkering their ideas into reality.
What that means is, from my understanding, that it offers tinkers a platform to make their own little robots or whatnot.
