I was curious just picked up a working 90001 did someone happen to test if the unit will run on 2s power or lower around 5v? I haven't looked as close to it like the 79001 trim info
Nope, look at my previous comment.

Hi, to answer the question about the board working on 5v, no it doesn't without modifying the mosfet and the fuses, i learned this the hard way, i modded mine via bypassing the 7805's and tried to run it in 5v, it worked for a small amount of time hissing then died, i assume the mosfet didn't tolerated the 5v and pulled more current than it's designed, but it proves the voltage converter driver seems to be capable of running on 5V, now i have a brick, could you please provide the pinout and/or the datasheet for the mosfet on 072-42? i checked the fuses and it seems to be okay, as it was working i assume that it only burned the mosfet, i have a couple motherboards with 5v and 3.3V gate mosfets to use as donor boards, i got a 8.5v external PSU from a fat, wich i'm fairly sure will work on this board too, thanks.

Thank you very much for this piece of gold, it didn't help my case but MAN i'mma help this dude in his saga, i'd always wanted to make exactly what he's doing but didn't feel like doing it alone, if you check my comment on the last page you'll see a big contribution to this wonderfull thread.
