I'm currently trying to figure out the Easy Driver V4.4 from Schmalzhaus to control a Stepper Motor. Okay, so I bought a Easy Driver V4.4 and a Stepper Motor.
The Motor needs max 280mA but the Easy Driver supports up to 750mA I think. To adjust that, there is a potentiometer on the driver board.
I need to measure the Voltage on Pin TP1 to calculate the current on the pot but can I destroy the Motor if the pot ist set to high from the beginning??? The documentation says that the pot direction can be different because sparkfun used a few different pots...great ^^
Thanks for any answer !!
