Epic Blockchain Universal Control Board Preview 

i connected to my s19jpro+ and i coudn't get my ip i was trying ip-report application no responed

Interesting concept- I guess you would have to compare the upfront cost of this board and how long before it would save over the % fees from other firmwares. And when you could actually buy it.

can this work with an l3+?

How universal are we talking? Whatsminer universe?
