 For our products we have chosen to use the RFDigital RFD22301 (previously RFD51822) product which has a nrf81522 chip inside. 
 Last year we discovered some issues with the module which proved to be related to the revision of the nrf81522 inside</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 14 Mar 2016 11:48:18 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/12438/nrf51822-revisions" /><item><title>RE: Nrf51822 revisions</title><link>https://devzone.nordicsemi.com/thread/47082?ContentTypeID=1</link><pubDate>Mon, 14 Mar 2016 11:48:18 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:aedecc77-2548-4987-9297-654145827000</guid><dc:creator>Hung Bui</dc:creator><description>&lt;p&gt;We have forwarded this question to RFDigital and got the response that RFDigital has handled this case directly with Leon.&lt;/p&gt;
&lt;p&gt;We just want to clarify that this issue is not in the scope Nordic can solve because it&amp;#39;s between the module maker, module’s distributors and the end customer.&lt;/p&gt;
&lt;p&gt;From our point of view there are possibly some reasons why the supplier still provides stocked Rev 1 module:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;pre&gt;&lt;code&gt;      This could be that the module includes custom firmware that runs on that version and the revision of the device is transparent and does not affect the user
&lt;/code&gt;&lt;/pre&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;pre&gt;&lt;code&gt;      Manufacture having to invest and put resources into updating firmware to reflect version changes.  
&lt;/code&gt;&lt;/pre&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;pre&gt;&lt;code&gt;      The potential need to recertify  if there was a Rev Change from Rev 1.  
&lt;/code&gt;&lt;/pre&gt;
&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;Note that if you contact RFDigital, they should be able to let you know how and where to get Rev 1 and/or Rev 2 module from different distributors.&lt;/p&gt;
&lt;p&gt;However, for new design we suggest our customer to move to Rev 3 as both Rev 1 and Rev 2 are discontinued.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Nrf51822 revisions</title><link>https://devzone.nordicsemi.com/thread/47081?ContentTypeID=1</link><pubDate>Wed, 09 Mar 2016 10:11:33 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:b5e9bfdc-55f6-42f3-ab80-398bbb63f95c</guid><dc:creator>Wojtek</dc:creator><description>&lt;p&gt;You can also order 32kB RAM version modules (if they exist)- they are for sure based on the newest chip revision, but probably are more expensive.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Nrf51822 revisions</title><link>https://devzone.nordicsemi.com/thread/47080?ContentTypeID=1</link><pubDate>Wed, 09 Mar 2016 10:10:08 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:f6851a61-b2f0-4a89-a213-04820e04e54c</guid><dc:creator>Leon Schmetz</dc:creator><description>&lt;p&gt;Of course you are right.
