https://devzone.nordicsemi.com/f/nordic-q-a/83669/custom-pcv-based-on-nrf52-dev-kitHi, I&#39;m designing a PCB based on the nRF52 Dev kit. I just need a BLE module with the nRF52832. My question is if I use the ports p19 or p20, do I really need the ATSAM3U2C? I just need to program the module for sending the data of some sensorsen-USTelligent Community 13Mon, 17 Jan 2022 10:55:18 GMThttps://devzone.nordicsemi.com/thread/347990?ContentTypeID=1Mon, 17 Jan 2022 10:55:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9fc82527-7323-45ee-8c0b-5f5ebd479129Charlie<p>Hi Pablo,</p> <p>The&nbsp;<span>ATSAM3U2C is a <a href="https://www.segger.com/products/debug-probes/j-link/models/j-link-ob/">J-Link OB</a>&nbsp;solution for our&nbsp;nRF52 Devkit, so you do not need to buy a separate JLink debugger for programming and debugging.</span></p> <p><span>It is not necessary for a real product, you can reserve a programming connector&nbsp;on your PCB or just use preprogrammed SoC.</span></p> <p><span>Best regards,</span></p> <p><span>Charlie</span></p><div style="clear:both;"></div>
