Reddit mentions of STEPPERONLINE CNC Stepper Motor Driver 1.0-4.2A 20-50VDC 1/128 Micro-Step Resolutions for Nema 17 and 23 Stepper Motor

Here is the link for my driver:

Also the power supply is 2.4A. Assuming A is amp

I am using these for a project, and so far I've been really impressed. I don't know the difference between the DQ542MA and DM542T

No, the adafruit PWM board by itself cannot run a stepper motor. It is only capable of producing the signals to drive a motor controller. You will need it to generate ~8 (depending on phases) high resolution PWM signals to run two stepper motors.

For a best performance setup I would recommend this:

STEPPERONLINE CNC Stepper Motor Driver (1/128 micro step) x2 ~$78https://www.amazon.com/STEPPERONLINE-1-0-4-2A-20-50VDC-Micro-step-Resolutions/dp/B06Y5VPSFN/ref=sr_1_3?keywords=stepper+motor+driver+micro+step&qid=1555450028&s=gateway&sr=8-3

NEMA 23 Stepper Motor x2 ~$160

There are cheaper ones with less resolution (1/32 microstep) and torque like this x2 = ~ $54https://www.amazon.com/Longruner-Stepper-Printer-Segments-LD09/dp/B07FK8NRKL/ref=sr_1_27?keywords=stepper%2Bmotor%2Bcontroller&qid=1555449504&s=gateway&sr=8-27&th=1

​

but moving 15lb with a stepper is solidly moving in on 3D printer / CNChardware territory.

You need to calculate how much rotational torque and holding torque your project needs. Then you will know how much stepper you need. Also how much resolution you are willing to pay for.

I'm going to put the links in a comment, I think they caused my post to get removed due to spam filter earlier:

  Don't necessarily have to use Amazon, but I'd prefer a US based company.
  
  Thanks!
