Our actual development boards do not use those pins either; they are only used for factory test. You could however leave them in the layout for mechanical strength purposes as done in our evaluation boards. Just notice Pin 63 should be connected to ground as described in reference manual (PA supply ground).</SPAN></P><P></P><P><SPAN style="color: #1f497d;">Moreover, if you would like to see the TWR or USB KW2x boards schematics and layout, you may download them from our website for free. They might help you in your custom boards’ design process. </SPAN></P><P></P><P><SPAN style="color: #1f497d;">Regards,</SPAN></P><P><SPAN style="color: #1f497d;">AngelC</SPAN></P></BODY></HTML> Tue, 18 Aug 2015 20:09:11 GMT AngelC 2015-08-18T20:09:11Z MKW22 Footprint https://community.nxp.com/t5/Wireless-MCU/MKW22-Footprint/m-p/445968#M663 <HTML><HEAD></HEAD><BODY><P>For the 8x8 MAPLGA foortpint should I include NC pads for the factory test pins 57-61 on the copper layer of my PCB as shown in the recommended footprint? or can they be omitted from the footprint all together?</P><P></P><P></P><P><span class="lia-inline-image-display-wrapper" image-alt="Capture.JPG"><img src="https://community.nxp.com/t5/image/serverpage/image-id/52495i0EFED7E5FF0BA3C7/image-size/large?v=v2&amp;px=999" role="button" title="Capture.JPG" alt="Capture.JPG" /></span> </P></BODY></HTML> Mon, 17 Aug 2015 16:55:18 GMT https://community.nxp.com/t5/Wireless-MCU/MKW22-Footprint/m-p/445968#M663 joelk 2015-08-17T16:55:18Z Re: MKW22 Footprint https://community.nxp.com/t5/Wireless-MCU/MKW22-Footprint/m-p/445969#M664 <HTML><HEAD></HEAD><BODY><P><SPAN style="color: #1f497d;">Hello Joel,</SPAN></P><P></P><P><SPAN style="color: #1f497d;">You could leave pins 57-62 disconnected.
