Hi mlattu,

Sorry, I can't give you the nRF9131-EK schematics. To be honest, I don't even think that this EK should be available to buy. Did you buy it or did you receive it directly from us ?

If you plan on making a product based on the nRF9131, I would highly recommend you contacting sales, as this chip is most likely not the one you want...

Now to answer your question, from what I saw, it seems to be safe to increase VDD_GPIO to 3.3V. You have to do it through the nPM1300 though, you can't just inject that voltage to the board.

If you have more questions on the nRF9131, please create a new DevZone ticket.

Best regards,

Simon

Good evening,

Would it be possible to receive a copy of the nRF9131-EK board schematics? I've managed to work my way through a few DevAcademy courses with this wonderful board, thanks to some tinkering and a few educated guesses along the way.

I'm currently trying to determine whether it's safe to increase the BUCK1 (VDD_GPIO) voltage from 1.8 V to 3.3 V without damaging anything on the board.

Are there any other components connected to this power rail that specifically require 1.8 V?

I'd greatly appreciate your help!

Hi,

I will check with the team if it's possible to share further details.

I know this page. But it's super limited. Can You send met at least the schematic of the board?

My board is : PCA10165 - 0.9.0 - 2024.26

Thanks,

Guus

Hi,

Please take look at this
