Equipment: Arduino Uno + DRV8825 + Wantai Stepper Motor 42BYGHW811
I have noticed (through purchasing more than twice), that the DRV8825 stepper motor driver is being sold on ebay and other sites with the pins attached and facing the wrong direction.
What I mean by the wrong direction, is that if you were to attach the heat sink to the correct side of the board, the heat sink would get in the way between the driver and the bread board. So you have to remove the pins, and replace them facing the other direction, so that the heat sink can sit ONTOP of the driver, and not below it.
Here are some images to better explain this issue.
For example, take this image (often used to sell the piece):
The driver on the left is how people are selling it and this is incorrect. The driver on the right is how I think it should be, so that you can attach the heat sink to the top. You cannot attach the heat sink to the top of the left one.
I don’t understand why people are selling this driver with the pins attached in the wrong direction. It would help if people could become aware of this issue and maybe sell them with the pins not attached. But as far as I have seen, most of the drivers come assembled incorrectly. I have only found one seller selling them with pins unattached so far.
I would like to know if anyone else has encountered this same problem?, and if so, what do you do to correct the pins, without damaging the driver? (as I have tried de-soldering them, but now i think I have over heated the board because I can’t get it to work yet)?
Thank you for your time and consideration.
