I have managed to get my hands on 4 FREE SLA7062M's. (had to begggggg for free samples! ). Anyone done anything with them yet!!!!
Nope but i am working on Phil's prototype 7051 board design. If the pinouts are the same you maybe able to use the same board.
They are not. 18 pin vs 21 pin

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
Reduced price for SLA7062M
I have the Allegro / Sanken SLA7062M Unipolar Microstepping Driver ICs for sale at the reduced price of $10 each. See: www.techkits.com
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
