https://devzone.nordicsemi.com/f/nordic-q-a/14850/pca10028-pinouts-on-nrf51822-evaluation-boardThe product specifications publication for the nRF51822 doesn&#39;t list a gull wing chip pinouts found on the PCA10028 found on the evaluation board, kinda wondering if there is an association I am missing?en-USTelligent Community 13Thu, 14 Jul 2016 04:33:38 GMThttps://devzone.nordicsemi.com/thread/56696?ContentTypeID=1Thu, 14 Jul 2016 04:33:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ed4336cf-555e-4686-980f-9be847f93a9cCap&amp;#39;n Tim<p>Oh, what happened was I was searching so hard for an answer I didn&#39;t see the obvious. Here&#39;s what I mean...when at the mBed complier website you can select a device. When I clicked on the nRF51 board it pops up and ONE of the tabs says: pinouts. There were the pinouts, very nicely labeled. Why I didn&#39;t notice that before...what can I say. As for the Nordic answer, I over-complicated the question so no wonder RK tried his best but didn&#39;t hit the nail on the head.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/56695?ContentTypeID=1Thu, 30 Jun 2016 01:39:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c36a0d10-5583-4a98-ae81-f11a34de5bd8RK<p>The product spec for the nRF51822 only discusses the minimum additional components required to support the chip, the PCA10028 is an entire product with many other components on it, most of them there for programming and interfacing.</p> <p>The schematics, BOM, user guide and fabrication files are all available from the PCA10028 downloads area if you want to see the full schematic. However the reference layouts for the nrf51422 and the diagrams in the product spec still tell you the actual minimum requirements.</p><div style="clear:both;"></div>
