Hardware description
Figure 25: nRF52840 interface switches
4.12 SIM and eSIM
The nRF9160 DK is designed to support both regular and embedded SIM (eSIM). For this purpose, it has
a pluggable SIM card socket that takes a nano-sized SIM (4FF) and a non-populated footprint for an eSIM
(MFF2).
Using the SIM socket is the default. If an eSIM is soldered on to the DK, switch SW8 can be used to select
the eSIM. Connector P23 can be used to connect and monitor the traffic on the SIM interface.
