Neither range works for > you? Thanks for taking a look at this :) I expect values to be magnitude of few hundred milliohms - which means micro-ohms should be usable. I'll try to still check this as I am far from being HW-expert. I probably can convert this to micro-ohms for v2.

BD9576MUF provides over-current protection and detection. Current is measured as voltage loss over external FET. Allow specifying FET's on resistance so current monitoring limits can be converted to voltages.
