I’m not sure about the wiring to the RB-Phi-210, and can’t find the answer elsewhere. I’m going to drive it with the A4988 stepper motor driver carrier. Would it be a good guess that:
green = 1B
black = 1A
red = 2A
blue = 2B
Thanks for helping me sort this out.
Hi,
That should be correct, the first coil wires can be connected on 1A (Black) and 1B (Green), and the second one can be connected on 2A (Red) and 2B (Blue).
Since, the RB-Phi-210 Stepper needs 1.7A current per coil , you might consider using the 8-35V 2A Single Bipolar Stepper Motor Driver A4988 Black Edition and not the normal version.
Regards,
Thank you sir, I’ll try it that way. Oh, and I am using the black version. I just soldered it in, and found that my VDD went from 5v to 4.5v, even though I’m using a 100mA regulator, and all it drives other than the A4988 is a uP and a couple parts which should load it to under 20mA. The A4988 data sheet says that it uses 8mA max - is that correct? Thank you.
Please ignore the comment about too much current. I soldered it in backwards. I saw the square pad in the corner, and assumed that it would be pin 1. Wrong!
Hi,
The square pad in the corner is GND. Attached is how to wire the A4988 Controller with the microcontroller, stepper and power supply.
Regards,
Thank you, I have it running now.
