Is it possible to access the extint pin on the current PCB design ?
If not and you go to a v2 design some time ahead, i’d love to get access to this pin for synchronized event tmestamping

Hi Matioupi,

Yes this pin is not available in the current version. It’s a good idea to add it in the next generation, I add it to the candidate changes. May I ask you what do you want to use EXTINT for?

e.g. timestamping camera strobe pulse for accurate positionning of a photo event (without any digital data delay issues). That’s the usual way to procceed with high end gnss receiver and airbone cameras

EVENTIN/TIMEMARK (EXTINT) is classically used in photogrammetry time-tagging and also to close the loop in time transfer applications.

Is there a chance that u-blox is able to allow firmware level reconfiguration of their GPIO (e.g. to swap EXTINT and geofence ?)
I actually matter more about EXTINT and that would let me use the feature within current ardusimple design…

We will check with u-blox next week

Hi Matioupi,

So we got some feedback from u-blox. Unfortunately is not possible to reconfigure the EXTINT function to another pin 🙁
In a few months we will do a small update to our board, and thanks to your feedback we have decided to add the EXTINT pin next to the GEOFENCE pin. You will receive a notification about it if you are subscribed to our newsletter.

Thanks again for all your inputs.
