Stepper Motor Controller Size Only 1.665*1.665*0.53 inch

I cann’t help to sharing a size only 1.6651.6650.53 inch Stepper Motor Controller with Microstepping, RS232 or CAN protocol.

Normally I just flag spam like this, but that seems like a pretty neat product. Could be a good option if I was making a CNC machine…

I notice that Sparkfun does not have a unipolar stepper motor drive. A simple, small drive can be made from a Sanken SLA7062M Unipolar Stepper Motor Translator/ Driver. This is a 21 pin module approximately 1 & 1/4" wide by 3/4" high by 3/16" thick. It can drive up to 3 amps output current and do half, quarter, eigth or sixteenth step operations. The only other components needed to drive a unipolar stepper motor are 3 resistors and 3 capacitors (no other Ic’s or transistors needed).

I got 6 engineering samples of the SLA7061M over a year ago but have never done anything with them because the pin spacing does not fit a 0.100" grid- it’s 2.08mm or 0.082". If sparkfun would do a conversion pc board for this I would be interested.

The data sheet is available at www.techkits.com/industrial/SLA7062.pdf and the prices on line are in the $2+ area.

You could always get a board made with BatchPCB - should only cost a few dollars...
