Mikrotik SXT Lite 5 AC is supported?

Hi, I need someone to tell me if the Mikrotik SXT Lite 5 AC are supported, I have seen the Mikrotik SXT Lite 5 if they are, but when I try to install OpenWrt on my device, I can not ping the address, nor can I log in in the console.

I have followed the steps of the Wiki again and again, but I can not install OpenWrt. I have tried several images .elf and nothing, I have also tried a custom compilation and the result remains the same.

I really need help, since the SXT Lite 5 AC comes with a RouterOS Level 3 license and I can not configure it as an AP.

Greetings, David.
