Accessing the USB data lines from the nPM1300EKhttps://devzone.nordicsemi.com/f/nordic-q-a/129167/accessing-the-usb-data-lines-from-the-npm1300ekIs there a recommended way to access the USB data lines from the J3 connector of the nPM1300EK? I would like to be able to charge the battery and also provide a USB mass storage device. It doesn&#39;t seem like the data lines are available via pins on theen-USTelligent Community 13Mon, 14 Sep 2026 13:40:06 GMTRE: Accessing the USB data lines from the nPM1300EKhttps://devzone.nordicsemi.com/thread/571197?ContentTypeID=1Mon, 14 Sep 2026 13:40:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:75e2ff18-feb3-4ffb-8b5e-2b5cf34c3e92Samruddhi Jadhav<p>Hello Patrick,</p> <p>J3&#39;s USB D+ and D- lines are unconnected on the nPM1300 EK and are not exposed on any header so there is no supported plug-in way to access them. For charging and USB mass storage through one connector, a custom board could route VBUS to the nPM1300 and D+/ D- to a USB-capable MCU. Please take a look at the following EK schematic and layout files here:&nbsp;<a href="https://www.nordicsemi.com/Products/Development-hardware/nPM1300-EK/Development-resources">https://www.nordicsemi.com/Products/Development-hardware/nPM1300-EK/Development-resources</a></p> <p>Let us know if you have any further questions.&nbsp;</p> <p>Best Regards,</p> <p>Samruddhi</p><div style="clear:both;"></div>
