https://devzone.nordicsemi.com/f/nordic-q-a/45397/default-uart-gpio-pins-nrf52832Hello, I am in the process of designing a new custom board with the nRF52832. Apologies for the silly question, but swimming in the documentation at the moment, and I need a foothold, so will appreciate any help.

We ship them blank, with no example code, so you program them yourself, by using a <a href="https://www.segger.com/products/debug-probes/j-link/models/j-link-base/">JLink</a> or similar external debugger, or with the debugger on an nRF52DK. So on your custom board you will need a pin header, preferably a 10pin header to fit a <a href="https://www.adafruit.com/product/1675?gclid=CjwKCAjwt8rMBRBOEiwA2F2biAvAioxaZdjWTcgkoD2Cw0xmGRXGjtFot0MWsPaFF7B457f6tywy2hoCLA4QAvD_BwE">10 pin SWD cable</a>, which is what fits the nRF52DK debug header.</p> <p>If you have any doubts on how to set this up, please refer to the DK hardware files which should be downloadable <a href="https://www.nordicsemi.com/Software-and-Tools/Development-Kits/nRF52-DK/Download#infotabs">here</a>.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
