https://devzone.nordicsemi.com/f/nordic-q-a/82081/nrf9160-reference-circuitryHey, Our custom board based on the reference circuitry in &quot; Product Specification v1.2 &quot;: We have been using the B0 revision of nRF9160 so far. Now we are planning on switching to B1 and I noticed that the reference circuitry has changed in the latesten-USTelligent Community 13Fri, 26 Nov 2021 14:48:13 GMThttps://devzone.nordicsemi.com/thread/340934?ContentTypeID=1Fri, 26 Nov 2021 14:48:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d24c7890-96ab-4201-b01a-3e41cca4a54fJared<p>Hi there,</p> <p><strong>We always recommend following the reference design, and I can&#39;t give any guarantees that it will work when you don&#39;t follow it.</strong> But I can do an educated guess, and say that it will most probably work fine using the ref design for B0 :)&nbsp; <strong>However, it&#39;s very important that the decoupling capacitor on Pin 13 is changed to 4.7 µF.</strong></p> <p>best regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
