https://devzone.nordicsemi.com/f/nordic-q-a/50617/nrf9160-esim-foorprint-and-flash-dataHello, I have questions about esim card. 1. Hardware footprint about esim chip. I don&#39;t know which esim chip I will use. So is there a common standard footprint? If yes I will use the standard footprint on the PCB board and don&#39;t need to worryen-USTelligent Community 13Tue, 06 Aug 2019 09:26:08 GMThttps://devzone.nordicsemi.com/thread/202555?ContentTypeID=1Tue, 06 Aug 2019 09:26:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:48e4c6ca-3fef-467d-84cb-1fdfc5ce1e3cMarjeris Romero<p>Hi,</p> <p>Usually when refering to embedded SIM (eSIM) we talk about a MFF2 form factor. If so, you can use the footprint used in the DK and follow the schematics in section 5.11 in the nRF91 DK user guide. You need lines SIM_1V8, SIM_RST, SIM_CLK, SIM_IO and GND to send data back and forth between the nRF9160 and the eSIM.</p> <p>You can read more information about eSIM technology in <a href="https://blog.nordicsemi.com/getconnected/the-difference-between-sim-esim-isim">this blogpost</a>.</p> <p>Best regards,</p> <p>Marjeris</p><div style="clear:both;"></div>
