+== Current Limiting ==
+The best way to set the motor current is by measuring the voltage on the Vref pin (0…2.5V) and adjusting the voltage with the potentiometer. The maximum settable motor current is 1.77A RMS (0.11Ohm sense resistors), but the SilentStepSticks can only be used up to 1.2A RMS.
+Irms = (Vref * 1.77A) / 2.5V = Vref * 0.71
+Vref = (Irms * 2.5V) / 1.77A = Irms * 1.41 = Imax
+Vref -> Voltage on Vref pin (Measure on Wiper of Potentiometer)
+Irms -> RMS (Root Mean Square) current per phase (Irms = Imax / 1.41)
+Imax -> Maximum current per phase (Imax = Irms * 1.41)
