micro-stepping types.
Note: The encoder value and the actual distance will depend on the diameter of the
wheel. For example, if user use 1/10 micro-stepping with motor 1.8

rotation. If the diameter of the wheel is 5cm, so
the distance for stepper motor to travel in 1 full 360
o
rotation is 2п(5cm/2) = 15.71cm.
Means, if we track encoder by sending 2000 to SD02B, it will stop the motor when it
traveled 15.71cm. For wheel with different size and stepper motor with different
resolution (
o
/step), the distance for the wheel to travel is different at 2000 encoder value.
User need to calculate own encoder value by referring to the formulae given above.
