External power supply and the level shifters to interface SIM class C and class B

Phuoc

Hi,

I'm looking for a solution to use a  SIM Card Power Supply With Level Translator for nRF910. Do you think this is possible?

Thanks.

    I got the following reply regarding using a level shifter:

    "From HW point of view I do not see any issue why this would not work. But for more

    detailed analysis of HW, we would need a schematic how they have setup the SIM interface"

    Could you share the schematics? You can do it in a private ticket (ticket 237063) if you prefer to.

    Best regards,

    Simon
