So, all the level shifting IO lines and clocking and such? Handy. I'll have to take a closer look at a Prisma board to see exactly what the FET would be doing (I have ideas). I am looking forward to the release of documentation.
Yes. The LDO output for IO and PLL are included as well.
The FETs help balance the voltage. For BE300 we may not include them, but we need experiment to see if it's true.
That's what I figured, the FET would act as a dummy load shunting extra current when the chips were underloaded in order to keep the string powered properly. Still like to see a hashrate/voltage chart or formula.
