Using OpenWrt on an EdtiskeLCX-ZJ1200-03

I've just got hold of an Edtiske LCX-ZJ1200-03, that looks like it's manufactured by Shenzhen Lingchuangxun Technology:

I can't seem to find any information about the hardware/chipset. Is there any way I can find out what it is and if I can install OpenWrt on it?

I'd return it.

Open it up.

You can't, at least not at the moment.
