I've read through most of the discussion on driving a Moonlite stepper (I have a CR2) and assume I can use a Nano and a L293D mini board. I'm a novice at this so could you point me to somewhere which shows all of the connections please, for example I'm not sure of where the connection on the attached hook up to the Arduino?
Could anyone clarify please - I'm almost complete but before I connect the power up I just want to be clear - J12 LD293D - B does that connect to the green screw terminals on the L293 (gnd & vin) common with the 12V to the motor?
from the main board going to the corresponding labelled connections on the LD293D mini. Then I have the two leads from J12 and I can't see where you mean these should go. If you could describe using the labels on the physical boards that would help me.
thank you for your patience.

Hi Robert,
I've read through most of the discussion on driving a Moonlite stepper (I have a CR2) and assume I can use a Nano and a L293D mini board.

many thanks,

in4 = d6
in3=d5
in2=d4
in1=d3
red = 4v
orange=input to lm78xx regulator
gnd to gnd of nano
Could anyone clarify please - I'm almost complete but before I connect the power up I just want to be clear - J12 LD293D - B does that connect to the green screw terminals on the L293 (gnd & vin) common with the 12V to the motor?

That connector has labels + - that one goes to the l293dmini 12v in and the other to the l293dmini nd.
The l293d will not drive unipolar motors.
Sorry Robert it isn't clear to me. So far I have

Thank you so much Robert, very clear and everything is working perfectly now!
No problem.
Hi guys, I have the proyect Up and running on windows machine, but would like to connect the focuser to a raspberry pi3b+ via usb, is it possible?
