Hi,
The BOM (bill of material) is ready.
I finished the netlist, footprint drawing, and footprint selection.
all available at : https://gsm.tsaitgaist.info/SIMtrace/v0.9+/
next task : place the components on the board (i'll try smart card size)
and route the lines.

I've just had a look at the the schematics and it looks fine to me now.

(i'll try smart card size)
and route the lines.
My guess is that it will be too hard to fit everything into smartcard
size (on a two-layer PCB with only one side of SMD components). But
feel free to try.
Regards,
Harald

It fits :). There is even some free space.
all the components are on one side.
The other side is only for gnd, and vias.

Hi,
The routing has been done.
Drawing and gerber are available.
As I never work with fabrication, I have no idea if I did it right/wrong.

Hi could you do a git status and add the missing files?
thanks

Hi,
there is not public git repo for SIMtrace (is there ?).
But I'm happy to push the one I have locally, if you wish and if harald
wants to setup a git for that.

Hi,
my mail server had an issue, I think this is one of the mails I lost. Oups.
Now the drawings are available in git (see in pcb folder).
Thanks for the forward,

Hi again,
thanks for pushing. Then let me repeat another question. I tried to look at
your SIM emulation but there does not seem to be any source in the repository
yet. Do you think you could share it?
11:32 p.m.
I already pushed some time ago, but it seems the git repo is down,
harald needs to repair it. (Correct me if I am just clumsy with my git
inexperience.)
I can send you the code meanwhile if you want.

What is the error you get on push? I could help you with permissions on the
git repo...

Hi Kevin,
I've had a look at the current .brd file and I think it's looking pretty
good.
My only comment: The P2 DEBUG connector only makes sense if it is a
one-row (1x6) connector that fits the existing ready-built FTDI cables.
Turning the connector into a 2x3 layout makes it mechanically
incompatible with those cables.
So either we keep it 1x6, or we simply remove it and force people to use
the 2.5mm jack.
Please let me know once you consider the .brd files finished, I would be
more than happy to order some pcb samples from pcbpool asap.
Regards,
Harald

changed.
not well aligned (does not fit well in the reserved space), but enough
for the prototype.
gerbers are also available
