The Raspberry Pi stepper motor and DC bonnet supports all Raspberry Pi computers with a 2×20 connection port and you can even stack multiple motor bonnets enabling you to use up to 32 for ...

By connecting the Raspberry Pi to a network of motor drivers, we can control the motors in realtime without overloading the Raspberry Pi. The original idea of the SlushEngine was to keep it simple.

An introduction to the Raspberry Pi 4 Model B computer, from how to set it up, to what you can do with it.

Rather than having the host Pi communicate directly with the stepper drivers, the 3+Pi features an onboard STM32F302CBT6 that handles the actual motor control.

With an STM32 microcontroller, TMC2209 stepper drivers, a Raspberry Pi Compute Module 4, and plenty of room for expansion, it promises to be a drop-in upgrade for essentially any 3D printer ...
