i have some stepper motors from old printers that have 6 pin header5, 5 wires and 4 coils like this one Mitsumi M42sp-4np in http://josafatisai.blogspot.de/2013/04/wiring-mitsumi-stepper-m42sp-4np-with.html, pins and wires are:
p1 Orange Coil 3
p2 Brown Coil 2
p3 RED VCC
p4 RED VCC
p5 Yellow Coil 1
p6 Black Coil 4
like
- could this stepper be drived by drv8825?
- what kind are the unipolar stepper motors that can be drived as bipolar stepper with drv8825?, could you name a example of it? have you a schematic of his coils?
best regards,
pescadito
