 I&amp;#39;m designing a board in which cost is a very important factor. I don&amp;#39;t need a lot of the GPIO pins of the nrf52840. Are there any 2 layer reference designs available for the nrf52840? 
 I also can&amp;#39;t find the download links for the nrf52840</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Wed, 29 Nov 2017 10:27:45 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/27668/nrf52840-2-layer-reference-design" /><item><title>RE: nrf52840 2-layer reference design</title><link>https://devzone.nordicsemi.com/thread/109219?ContentTypeID=1</link><pubDate>Wed, 29 Nov 2017 10:27:45 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:eff163aa-7773-4fe6-bcda-257b180dce5e</guid><dc:creator>dpape</dc:creator><description>&lt;p&gt;Hi Jørn,&lt;/p&gt;
&lt;p&gt;Thank you for your fast response. I will contact my regional sales manager.&lt;/p&gt;
&lt;p&gt;Kind regards,

&lt;p&gt;Unfortunately, we do not have any 2-layer reference designs for the nRF52840 at this time. Doing a 2-layer design can be very difficult though as it, at least as of today, only comes in the QIAA package, so routing the traces from the inner row of contact points can be a problem. For more information on packages, please contact your regional sales manager. If you do not know who this is, please message me your location and I will provide you with contact details.&lt;/p&gt;
&lt;p&gt;The hardware files for the nRF52840 preview kit can be found at the bottom of the downloads tab of the &lt;a href="http://www.nordicsemi.com/eng/Products/nRF52840-Preview-DK"&gt;nRF52840 preview kit&lt;/a&gt; product page.&lt;/p&gt;
&lt;p&gt;Best regards&lt;/p&gt;
