Fantastic!
Great that the changes are focused - just adding a BOM that people can use to order parts for the v3 board that's currently on OSHPARK makes sense as a first step. Also, it's really really nice from a review point of view, and for clean history when each commit of a PR does one focused thing like this IMHO.
One question: should the component info be in project_components/parport.lib
? I'm still trying to wrap my head around what a stable, standalone KiCAD project looks like in github so your thoughts would be appreciated.
Since you took the trouble to make a github markdown table for the BOM would you like to go ahead and add that to the PR as a separate commit that drops it in hardware_v3/BOM.md
with a link from the main README.md
?
Then this PR can close #32.
Again thanks alot!
Yeah, I think the component info should also go in the local library files like project_components/parport.lib
. Ideally, it would have been put in there in an early stage at least for chips and the like, resistors and capacitors may have the part numbers added individually. I think I'll add that in quick.
Definitely, I'll add hardware_v3/BOM.md
and also make note of the standoffs and screws there like v2 did.
Speaking of capacitors, the V3 design is missing one as per #28, but I'll add a note about this in the BOM.md
while I'm at it.
For the sake of consistency with the v2 Bill of Materials, I've also added the Package, Description, and Notes fields.
This looks perfect @quorten. Ready to merge?
@garlick Sure, I'm ready. Closes issue #30... looks like you've accidentally reference the wrong number earlier.
Oops, not yet, I've noticed I got the table headings mixed up on the BOM part listing the mounting parts. I'll push a quick fix.
There we go, now I'm ready, there was an extra table column in the last table, but only in the header.
Thanks again!
Add manufacturer part numbers for all components. All of the selected parts are available on Digi-Key and the field "Digi-Key_PN" was also added for the Digi-Key part numbers, just like the KiCad Digi-Key parts library uses. I opted to pick some of the better parts for the pin headers... higher temperature insulators on the pin headers, gold-plated mating contacts for the large pin headers. Likewise, I picked Panasonic resistors since they end up being the same price as the cheapest except when bought in bulk.
Also I've added a link to the datasheet for the CAT24C32 EEPROM.
Here are the condensed results of generating the BoM:
N.B.: Digi-Key subtotal today says $6.73.
