i would like to power 3 stepper motors and at the same time have current sensors.
In my intended circuit, i have 2 stepper motors (ratings: 5V, 0.57A/phase) connected to an INA219 high side current sensor which is then connected to the motorshield
i also have another stepper motor (ratings: 5.6V 0.67A/phase) that is connected to an A4988 motor driver and then connected to the motor shield
1) does the A4988 motor driver have its own in built current sensor? if it doesn't then is it possible to connect an INA219 current sensor to it? or is there an easier way?
2) what is the best way to power such a circuit? i was intending of having 3 external power sources that would power each stepper motor but i read on the forums and i could use the arduino supply but i must remove the power jumper? (i'm not too sure about this)
