]]>For the 12V, I tested with 12V 2 A and 12V 3 A. But even if the Nema does not move, the engine driver heat enormously. With more amperes, I imagine he would have more heat.
Thank you

For those who like me, the same problem is that no one helps.
Here is the solution I found that worked for me.
The card did not work any work done on it. So I used this diagram (see image at the bottom of the page). But the 12 volts did not work either, regardless of the Stepper Driver used. So I used a 5Volts 4 amp power supply for the POLOLU-2134 DRV8834.
And that to work.
If it can help someone, it is with pleasure.Thanks to Minautor who made me discover this schema on the forum

What power supply where you originally using? It's common knowledge that all Pi's from the B and beyond require a minimum of 2.5 AMPS just for them to work. That does not include the Amperage needed for the other components in your system. Ideally the motor should have a separate higher voltage and current supply like 12 volts at 5 amps. But if you run the entire system from a 4 volt supply then it would stand to reason that 4 amps would work but I would honestly use 6 to 10 amps just to make sure there was some over head. Since the motor is using that supply as well.
