Hey, I want to build a self-balancing robot. I use a Arduino Nano clone to control my Nema 17 stepper motors. For the drivers I use the a4988. I have a 12 V voltage source, but I only use 7 V for the VIN-Pin (through a voltage divider). Now the problem I have is that my Nanos only survive for a day…

I want to build a balancing bot, but my Nanos burn out

Oh, thats a good point!
My steppers have a maximun of 1.5 A and i adjusted the drivers to reach 1.3 A.
