I'd like to measure the voltage at a test point on a stepper motor driver chip with an arduino. The voltage at this point controls the amperages to the phase coils and is adjusted to trim the driver.
I have a common ground with the driver already, I'd like to wire the drivers v-ref point to an analog input to drive an LCD showing the output amp number so I can adjust the driver.
The issue I am worried about is that with the hardware I have to test with a properly trimmed driver is pushing 0.84A.
Is this safe to do without killing the arduino board?
