How to connect Stepper motors?

I want to connect three stepper motors. Is there any stepper motor controller that I can buy to interface using I2C/SPI with the OpenMV?

See this:

We’re a MicroPython board. So, any MicroPython library will work. Note that CircuitPython is not the same as MicroPython.

Thank you

There are 8 PWM in your servo shield. Can I use 6 of the PWMs for 3 stepper motor?

Yeah, I suppose so, you just need to modify the library code to work for that. Our servo shield has two driver files. One to control the PCA chip and another to implement servo control code on top of that.
