His 3+Pi board attaches to the Raspberry Pi’s GPIO header and gives you a convenient way to control four individual stepper motors.

The Raspberry Pi bonnet can drive up to 4 DC or 2 stepper motors with full PWM speed control offering a great solution for robotics, DIY milling machines or 3D printers.

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.

When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, ...

The blinds themselves are hooked up to the Pi with a Stepper Motor HAT and powered by a small motor. This isn’t an easy project and it’ll take a lot to adapt it for your own usage, but it’s ...
