Easy Stepper is a quick and simple way to test Polou/StepSticks or stepper motors and mechanical assemblies such as stepper driven gearboxes and linear activators.
Make sure to orient the Pololu/StepStick correct (see the picture with varies types of StepSticks).
Please note the Pololu/StepStick is not included and it's needed to drive any stepper motor.
Just hook up whatever power supply (between 8 and 24V, AC or DC) you have lying around to the screw terminals or the barrel jack connector and whatever stepper driven device you have to the motor output pin header or screw terminal and you are ready to go.
The controls are really simple. When the potentiometer is centered the stepper motor will stand still. When the potentiometer is turned clockwise the stepper motor will start turning in one direction. The further you turn the potentiometer the faster the motor turns and when you turn the potentiometer back the stepper will slow down again. When you turn the potentiometer counterclockwise past the center the stepper motor will start turning in the other direction. The two buttons are for fast forward and fast backwards. With the MS1-2-3 jumpers you can set the microstep resolution on the Polulu/Stepstick. The Use-Enable solder jumper should not be used with the standard firmware.
The RAPS 128 does not have an inverted input signal on the Enable pin like regular stepper drivers. This means that the Enable pin needs to get pulled up to 5V instead of down to GND for the stepper driver to work.
This can be done by making a connection directly from 5V to the Enable pin on either the Easy Stepper or the stepper driver itself.
Doing it on the Easy Stepper will make it incompatible with regular stepper drivers (until changed back) so we recommend doing it on the stepper driver instead.
Input: 8 to 24V AC/DC Output: Depending on the Pololu/Stepstick and power supply you are using. Size: 40X60mm MCU: Attiny10
Reprogramming the firmware
You can reprogram the Easy Stepper with a AVRISP MKII programmer through the programming port on the backside of the Easy stepper. AVRISP mkII
