Please can any one tell me if I have to put a resistor ( my motor uses 1.5 Amp) between the Step motor and the gecko drive.
Or between the gecko drive and the power supply.

Also I know that I have to put a brakeout board. I'm building the 4 axis Minmo board. My question is. Does the Gecko drive has built in opto-isolators, it is necessary for this drive, or I have to make some changes to the Minmo board to
put the opto-isolators.
Or Minmo board doesn't fit my Gecko drive.
I really want to built the brakeout board.

Sorry about my bad english
