uStepper – Controlling Stepper Motor with ease




But what is uStepper?

In short, uStepper is a product, improving performance of a motor type called “stepper motors”. Stepper motors are used in a wide range of applications where you have to move something, a certain distance, precisely! For example, they are used in your inkjet printer for moving the ink cartridge back and forth over the paper. Stepper motors are precise and really cheap compared to the alternative, Servo motors.

There are one drawback of the steppers though – you actually can’t tell if they move to the position you tell it. If you try to block the path of the ink-jet head, while your printer is printing, it will not recover from this. The printer is rather dependent on the stepper operating with high precision so that you get something readable on your paper!

The same happens in most of the applications using stepper motors, including 3D printers where the type of steppers, which uStepper is designed for, are primarily used. What uStepper does, is that it removes this drawback by continuously monitoring where it is, and where it should be. Thus, uStepper can compensate if anything goes wrong – this is what we call operating with feedback.

uStepper both has the ability to drive the stepper motor, monitor position and has an onboard programmable microcontroller with a wide range of available inputs and outputs. All this is packed into a very small printed circuit board that fits right on the back of those small stepper motors (which are referred to as NEMA 17).

To make uStepper accessible for both professionals, hobbyists and students, it is compatible with the Arduino IDE. Here you can easily program your uStepper to do exactly what you need it to do!

Who is the target audience for uStepper?

As mentioned previously uStepper is Arduino based and addresses both students, hobbyists and the technician/engineer making for example a test-setups. We focus a lot on the educational sector and have made a product which we believe makes learning with Arduino a lot more fun! Besides the uStepper board, we have made an application example – the uStepper Robot Arm, which gives uStepper a new dimension and addresses the more advanced users. We have sold the uStepper and the uStepper Robot Arm to several Universities around the world, including Aalborg university where we still have a close bond to the professors and employees.
