Curent calibration with voltmeter
The driver calibration is to be made ideally using a voltmeter
Use the 2VDC caliber (or something close) on your multimeter.
The voltages we are going to read are below 1V
The following formula is to be applied
IMotor= Vref * 2 for RS= 0.1ohm
Here is a simple table with all the common values

0.1V 0.2 A
0.15V 0.3 A
0.20V 0.4 A
