shahidmk, I have developed a circuit board for the SLA7062M unipolar microstepper IC. The STEP & DIRECTION inputs are opto-isolated and can be configured as PNP sourcing or NPN sinking. It has and idle current reduction feature that reduces motor current by 50% when no step pulses have been received (after a 2-second delay). The motor current is adjustable to 0.5 Amps to 3.0 Amps with a potentiometer and the board accepts an input voltage range of 10 to 44 VDC. The board size is 2.8" x 3.7" Both the boards and the SLA7062 IC's are available at: www.techkits.com -DW |

| Hello to all We made it a circuit with SLA7062M and shoot SLA7062M and smoke. ![]() That happens when I want to increase motor curent for more than 0.5 A. Stepper is 5V to 0.8 A I attach the circuit if someone clarifying its Excuse my English idiot |

| If you can send me a schematic and board layout in .jpg formats, I could have a look at them for you (it may be after my holiday in 2 weeks time though!) I do not want to install Eagle on this laptop.....sorry.... regards Der fisherman. |
