General • Re: RP2040 pull-down resistance below data sheet ranges

If you want a voltage divider, build a voltage divider, and turn the pull-ups or pull-downs off.

I am tight for space on this board and was hoping that I could use the input pull-down resistors as part of the divider.

I understand that they're not really resistors, and that there is significant specification spread on their behavior because of process variation.

But I do think that the published values for these "resistors" should reflect reality.

I do have a Keithley SMU; perhaps I will get some V/I curves from these inputs and publish them.
