https://devzone.nordicsemi.com/f/nordic-q-a/71331/rsource-vbus-specification-discrepancyThe v1.3 Product Specification datasheet for the nRF52833 lists the maximum source resistance on VBUS, including cable, as 2 ohms. Yet the same document recommends using a 4.7 ohm resistor in the VBUS line to add protection against transient over-voltageen-USTelligent Community 13Fri, 05 Feb 2021 13:28:43 GMThttps://devzone.nordicsemi.com/thread/293103?ContentTypeID=1Fri, 05 Feb 2021 13:28:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f2b922d1-d9a2-4014-9e40-46183c8fd94fSimonr<p>Hi</p> <p>This seems like outdated information has found its way into the specificaiton. 4.7 Ohm should be fine (and is recommended in our latest reference layouts).</p> <p>I have contacted the tech writers to take a look at this. Thank you for notifying us!</p> <p>Best regards,</p> <p>Simon&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;</p><div style="clear:both;"></div>
