Stepper library for wemos d1 mini shield needed

Hi,
recently I’m working on a window roller blind project operating at homebridge. I managed to create such blinds based on nodemcu, everything works great in homekit but now I would like to miniaturize everithind as much as possible. I found in my drawer wemos d1 mini and wemos d1 mini motor shield 1.0. For some reason, Wemos does not want to cooperate with stepper 28BYJ-48. I guess it's a problem with the motor shield library. I searched half of the internet but I haven’t found anything.

Has Anyone a library for wemos d1 mini and wemos d1 mini motor shield that supports stepper motors?

Did you ever find anything? I'm interested in using a D1 mini with the motor shield & a stepper motor for a project.

Assuming you are using the usual ULN2003 driver for the 28BYJ-48 stepper motor then there should be no need for any motor shield.

However I don't know if the ULN2003 will work with 3.3v signals from a Wemos.

I have used the ULN2003 to drive the 28BYJ-48 from an ESP32 at 3.3V logic and powered the driver with a separate 5V source.

Everything seemed to work well.
