This is my first PCB design so I'm nervous about giving out much in the way of details.
Well, I know the feeling, it's very understandable.
About a shield for the nucleo, my suggestion is to take care about input pins and EXTI lines interrupts (see the wiki for more details). You want to avoid to have on the same interrupt line, 2 inputs pin that use interrupt .
Also, I have jus

Thanks newbob for your hints,
effectively I am using that shield to make some tests with a cheap scope, some driver and a stepper motor I have.
Indeed, as I pointed out in the first post, I have tried to keep the pinout as similar to the arduino as possible to use a shield... that is practically the one you posted.
There are just a couple of inputs that are reconnected on the morpho pins (the

Thanks for sharing your work. I don't have a nucleo board right now but they certainly have a lot of untapped potential. Keep it up!
Thanks!! I hope it could be useful to many peoples. I already have in mind small improvements, but I hope sharing the project may suggest bigger improvements

Hi guys,
I am new in the forum, but I read it before every now and then.
A bit of time ago I obtained a NUCLEOF401RE board, that is quite cheap but powerful, and I played with it and with GRBL and some motors I had, and I started porting the GRBL v.0.9 code on the cortex processor.
After a bit (or a lot ) of work I have been able to port the code, and I did a bit of testing with some GCODE fi

Ciao a tutti,
sono nuovo del forum, anche se da disiscritto ho letto un po' di topics e di info per saperne di piu' riguardo questo affascinante mondo.
Qualche tempo fa mi sono ritrovato a disposizione una scheda NUCLEOF401RE che e' una board abbastanza economica, e volendo giocare con i G/Code e qualche motore a mia disposizione, ho iniziato a portarmi il codice GRBL v.0.9 sul processore corte
