Looking for SIM footprints

Hi all,
I have to do a SIM card adapter like the photo below (picked-up from the web).
Do you know where I can find the SIM fooprint to realize a PCB?


What is the part number?

You didn’t specify which SIM size?


You’re after this part, right?

Thank you for the quick responses,
so I was not clear in my request (English is not my mother tongue)

I looking for the PCB footprint of the SIM pads

I want to make adapter for micro-sim and nano-sim. They have the same footprint, only the cuting edges are different.


Right, Joan_Sparky :wink:

Looks like it’s buried in some ISO norm and no one ever managed to get a copy of a drawing out of there.

Via google I can find nano sim contact dimensions and also some mini to micro relevant specs, but nothing from nano to micro or nano to mini.

Thank god for norms and paywalls, right?

I adjusted the title, maybe someone has had more luck than me. I tried for 10mins and gave up.

PS: I’d get a couple of card photos (not drawings!) from the mini sims into a paint prog, the higher the resolution the better and then start ‘counting pixels’ vs. what the outside dimensions of those cards are. Some math and you will get there.
Or as they say where I come from - Mühsam ernährt sich das Eichhörnchen.

Not sure if these are what you are looking for:

Micro SIM 7pin.pdf (201.1 KB)
NANO SIM.pdf (220.6 KB)

He’s looking for the footprint of the SIM itself; not the connectors. I haven’t found the official spec, I guess that is only of interest to manufacturers of SIM cards and connectors.

However, it seems that the pads are on a 0.1" matrix, width 0.3", so it’s simple enough to create a footprint. The pads are labelled C1 to C8. An unofficial datasheet for standard SIM

similar info for micro and nano cards is also around. The nano moves C4 and C8 (which seem to be optional anyway).


Doh! That should have been obvious but I was a little slow on that one. :confused: I’ll try to do better next time. :slight_smile:

what i found is this, but i don’t think it is the right one: https://github.com/Agilack/contrib-kicad_parts/tree/master/conn-sim

or this: https://github.com/zwizwa/simtrace/tree/master/hardware/kicad/lib

i hope it helped.

Recently, I have needed SIM Card (UICC) form factors to create PCB converters.
The information could be found in ETSI Specifications ETSI TS 102 221;
