https://devzone.nordicsemi.com/f/nordic-q-a/73019/schematic-symbol-drawing-standardOn Nordic reference schematics the nRFxx symbols are designed with pins in all directions (up, down, left, right) with the pin numbers 1,2,3.. placed in a &#39;PCB layout view&#39;. This is not according to &#39;normal&#39; ways of designing schematic symbols whereen-USTelligent Community 13Fri, 19 Mar 2021 13:38:57 GMThttps://devzone.nordicsemi.com/thread/300953?ContentTypeID=1Fri, 19 Mar 2021 13:38:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:69ce1923-e68f-4cad-86ba-88cf26bea687Kaja<p>Hi Rune,<br /><br />we have always done it in this way, because it&#39;s easier to relate to the mechanical drawing and the physical placement of the pins on the chip.&nbsp;<br />This also makes it easier to see where you should place the right decupling capacitors in the layout.&nbsp;<br /><br /><br />This is not done in our newest reference design for the nRF53 series.&nbsp;<br /><br />Best regards,<br />Kaja<br /><br /></p><div style="clear:both;"></div>
