In general, the essence is this - there is a motor-shield based on L293D
But it does not hold current for powerful steppers like NEMA23 425oz 6.4V 3A

But I have IRF7389 lying around and kind people suggested that they can solve the problem ...
And who would be kind to finish it like me connect these IRF7389? I'm even attaching a picture - just draw the necessary lines. And yes, I myself am not boom-boom in this you, it just so happened ...
