Request: Provide XLS BOM?
Hi there! This project looks great! My only request is to upload an XLS BOM so that people who don't want to source the individual surface mount components can just have the fab assemble that part.
Thanks for your hard work!
Will work on it. The BOM that Kicad generates is not that useful. I will create something manually. Not too many parts to list.
Added BOM. https://github.com/zapta/simple_stepper_motor_analyzer/tree/master/kicad
Crap, I forgot, they also need a CPL (pick and place) file. If that's not easy for you to produce, a exported .zip from kicad (project, not gerber) will let me generate them in EasyEDA.
Ben, is this is what you are looking for? https://support.jlcpcb.com/article/84-how-to-generate-the-bom-and-centroid-file-from-kicad
I can try going over the instructions and export. BTW, I looked at SMD service at JLCPCB but am not sure they have the exact Alegro current sensors.
Yeah, that's it! Hmmm you checked on LCSC.com? That's unfortunate. I wonder if I'd have better luck through PCBway?
@bepstein111 Did you have chance to generate that CPL file?
I found Alegro current sensor at https://www.aliexpress.com/item/4000178092630.html
Be very careful of aliexpress vendors. There is a reasonable chance you will get a fake chip. Personally, I would not trust them - way too many stories of remarked chips that aren't even close to what they claim to be.
Here is another one. This is witha a different package that most makers would consider easier to solder (will require a minor PCB change).

FYI, I just released an upgraded design which is based on the Raspberry Pi Pico. It also includes gerbers, bom and pos files for JLCPCB SMD service, for the parts they do carry.
