https://devzone.nordicsemi.com/f/nordic-q-a/76697/question-for-nrf52-dkHi team, My customer is working on a design with nRF52832, and they look into several reference layout, one question comes from our nRF52-DK, they want to know why 12pf in P0.26 and P0.27? What is the function of those and how to select the valueen-USTelligent Community 13Mon, 22 May 2023 13:45:08 GMThttps://devzone.nordicsemi.com/thread/426609?ContentTypeID=1Mon, 22 May 2023 13:45:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e48b7330-a010-44d2-b552-311b4a0cbee0Bendik Heiskel<p>Hi Seba,</p> <p>The errata fix is included in the reference design files but not shown in the product specification.</p> <p>You can download the design files here:</p> <p><a href="https://www.nordicsemi.com/Products/nRF52832/Download">https://www.nordicsemi.com/Products/nRF52832/Download</a></p> <p>&nbsp;</p> <p>Best regards,</p> <p>Bendik</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/426147?ContentTypeID=1Thu, 18 May 2023 12:00:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ceba1886-7b07-43be-b21f-983a2d643cfbSebastijan<p>Hi Nordic,</p> <p>Why this is not mentioned in reference design in product specification, or did I overlooked it?</p> <p>Regards.</p> <p>Seba</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/317507?ContentTypeID=1Mon, 28 Jun 2021 13:42:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:73d51b9d-8537-4a01-921e-656857462218Bendik Heiskel<p>Hi Leon.</p> <p>The inductors L2 and L3 have a minimum current rating of 50mA.</p> <p>Best regards</p> <p>Bendik Heiskel</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/317406?ContentTypeID=1Mon, 28 Jun 2021 08:51:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e53c68a7-97a8-4e91-83f6-8c26ef6088c9LeonWu<p>Hi Bendik,</p> <p>Another question from customer, what is the current of 2 capacitors via DCC in working mode?

If the pins are not needed for GPIO, it is more effective to short the pins to ground directly.</p> <p>Best regards</p> <p>Bendik Heiskel</p><div style="clear:both;"></div>
