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've asked internally about this and I'm currently waiting for an answer.

Best regards,

Simon

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
