Gerber files #19

Closed jeroentaverne closed 2 years ago

jeroentaverne commented 2 years ago

Hi. Are there some gerber files available for this project? I know it can be hand wired, but a real PCB will make it look much nicer. Thanks!

tomtebloss commented 2 years ago

I did fork this out and made some PCB: https://github.com/tomtebloss/acsi2stm/tree/master/gerbers

Hey, thanks for the gerbers, just a note: the R3 is 10k not 100k. With 100k you can't set the programming mode. BOM needs fixing pictures are showing correct resistor.

tomtebloss commented 2 years ago

Thx for pointing it out. I changed BOM and readme. I changed R4 to 10K as well since it is also part of the programming mode but not really used in out project.

EDIT: 1003 is 100K. Changed back in BOM and new picture is uploaded.

@tomtebloss No problemo, big thanks for gerbers - I've finished soldering first one and now trying to cope with my STM32 version which is odd - seems to be either not starting the official build or my compiled version, but kind-of works (shows up as multiple ADAPTEC 5500 controlers) with this binary: https://github.com/retro16/acsi2stm/issues/15#issuecomment-968469499

@tomtebloss One more question - the R2 on your photo is 1K while BOM states 10k. Should it be 1k as well?

I'm unsure which photo you mean? Schematics says 10K and the photo is 1002? A 10K right?

Anyway, it's part of the reset circuit along with C2.

luciust commented 2 years ago

@tomtebloss Yeah - correct the 4 digit mode - yet if photo is correct - then BOM says: R2, R3 are 10k , while on the said picture we have R2 @ 10k and R4 @ 100k. My fault I got confused with my 3 and your 4 digit code - but I would say that BOM and R2,R3 and R4 vs picture - need your eyes. I'm debugging the fake STM32 - thus looking at each small piece on blue pill vs gerber too...

tomtebloss commented 2 years ago

Here is the schematics I used (if I remember correctly) of the "bluepill" when I designed my board. Apparently R10 should be changed to 1.5K. So I will probably change that at least. I didn't use USB for programming. Only for power.

I will have to change some resistors and try mine out first and then take new photos.

EDIT: R2=10K (1002), R3=100K (1003) and R4=100K (1003) as the schematics says. BOM and readme is updated. R10 is changed to 1.5K as recommended.

Thanks! I needed that!

Version 3.00 now provides an official PCB. Closing this issue.
