Goooooooooooooooooooood afternoon, or morning, or night. It depends on were do you live.

Ok, status, I savaged some parts from a old printer, I'm trying to make the motors work (MITSUMI M49SP-1 7.5ºSTEP 4OOHM) and I need a driver! It only has 4 wires so I assume it is dipolar (?)

I found these
(1) https://www.banggood.com/pt/CNC-Shield-4-X-DRV8825-Driver-Kit-For-Arduino-3D-Printer-p-1134939.html?gmcCountry=PT&currency=EUR&utm_source=googleshopping&utm_medium=cpc_elc&utm_content=felix2&utm_campaign=pla-all2-pt-pc&gclid=CjwKCAjw68zZBRAnEiwACw0eYeN9X_pGR9n4JHxo_eD9KAtkllO8WYftschW2j1hr3h6bRkahC8f_RoCFnwQAvD_BwE&stayold=1&cur_warehouse=CN

(2) A3967 Module EasyDriver Shield Stepping Stepper Motor Driver for Arduino for sale online | eBay

Will one of these work? And how do I get the sofware needed? Need some info folks!

Many people use the Grbl firmware for their CNC machines. The Pololu site has information on the DRV8825.

The DRV8825 can supply a great deal more current than the A3967 in an Easydriver. About 1.7 amps compared to less than 0.7 amps.
