StepDuino Stepper Motor Controller

Online Special: $49.00 Normally: $139.00

The StepDuino is a complete, self-contained Arduino-compatible board with 2 onboard stepper motor drivers, 2 servo outputs, a 20x4 LCD, a micro SD card slot, and more!

It's a fantastic general purpose board for any project that uses stepper motors. You can use it as the brain of your next robotics project!

The StepDuino uses the same processor architecture as the common Arduino Uno, so you can program it right from the Arduino IDE simply by selecting "Arduino Uno" as the board type. Everything simply works out of the box, just as it would with a regular Arduino - but now you can also drive steppers directly and display feedback on the huge LCD.
