The nRF9160 VDD VDD_GPIO is powered by 3.3V so the nRF7002 VBAT/BUCKVBAT/BUCKVBATS/AFEVBAT and IOVDD is also powered from theen-USTelligent Community 13Tue, 14 Mar 2023 14:50:11 GMThttps://devzone.nordicsemi.com/thread/415271?ContentTypeID=1Tue, 14 Mar 2023 14:50:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:aee3b780-fe6e-49d4-b295-164d783e86e3ketiljo<p>No, the IO levels must match the IOVDD level.&nbsp;</p> <p>Also, the MAGIO, SCKL and SDATA is controlled by the modem and the application has no control over those.&nbsp;</p> <p>You need to either free up some GPIOs, use a mux or a port&nbsp;expander.</p><div style="clear:both;"></div>
