https://devzone.nordicsemi.com/f/nordic-q-a/113283/pr2401Hello : Refer to your official schematic nRF52832-DCDC circuit, VDD has a total of 3 pins, 13/36/48 pins. We found that the default capacitors were different. 48pin was configured with 4.7uF, while the other two were configured with 100nF. Why the differenceen-USTelligent Community 13Tue, 23 Jul 2024 08:58:25 GMThttps://devzone.nordicsemi.com/thread/495161?ContentTypeID=1Tue, 23 Jul 2024 08:58:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d0bedfb5-8b42-4a9a-b701-1ee5ce8d91e4ketiljo<p>The internal regulators are connected to this pin.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/495108?ContentTypeID=1Tue, 23 Jul 2024 01:02:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:150d1be0-5bbf-475f-9e18-2078f8eb25eaHuiHuang<p>&ldquo;<span>Pin is the main connection</span>&rdquo;</p> <p>-----</p> <p>Which pin is it, and why is it primary?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/495037?ContentTypeID=1Mon, 22 Jul 2024 13:28:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e84a94f0-0b66-4476-a6a2-ff7460698625ketiljo<p>The VDD pins are internally connected but must be externally connected as well. Pin is the main connection so the 4.7 µF cap shall be placed here. The smaller caps are decoupling caps.&nbsp;</p><div style="clear:both;"></div>
