Instead of Leonardo and BrainShield, I used the same as you a perf board, 2x A4988, ESP8266, MPU-6050 and Arduino Pro Micro.

I changed in software port 12 with port 9 and software is running, motors are spinning, I am not yet finished with mechanical parts so I can not tell if everything fits and works as expected. But I was able to realize that the software is working only if the USB cable is connected to Arduino Pro Micro and Serial monitor is open.
Can you give a hint how to solve this?

Steppers are from jjRobots bought, so NEMA17.

I used the source code from here:
https://github.com/jjrobots/B-ROBOT_EVO2

Hi,
i would need to know what you change exactly moving from port 12 to port 9 of Pro Micro; in any case the connections to MPU 6050 are too long ( timing is critical ). What do you mean " the software is working only.... etc...".
If you want i can send by email my modified code and full electrical diagram of my little robot, which use the same hardware of you.
Keep me informed.
Regards, Carlo.

Hello Carlo, if it is possible to receive from you the complete schematic and code, would be great.

The software starts only after programming with Arduino Ide or when i open the serial monitor, if i plug the battery, software is not starting.

Right now i placed the ESP8266 and connected it like in the brain shield. I keep getting timeout from communication between arduino pro mini and ESP8266
Hi,
i dont know the connections of your project, but dont supply external voltage to Micro board on the same time from USB !
Please send me by forum your email, and i will send my project to you.
Regards, Carlo.
