Hi there! 
Please, help me to determine what model of RouterBOARD it is?
RouterBOARD has one Ethernet, two miniPCI, CPU - AMD Elan SC520-133AC.
Any help is greatly appreciated! Thank you!
it is not RouterBOARD. And not a product of MikroTik.
Looks like this Soekris SBC: http://soekris.com/products/net4526-product-range.html
It is not a RouterBOARD.
Oh, thank you guys!
I decided that it’s RouterBOARD because license RouterOS (x86) was installed on this board. I was wrong.
