None of the datasheets are up to date.

ST and Johnson have for both packages. Doesn&#39;t matter what revision you have. Just get the one for your package type.</p> <p>When you say &quot;The list of nRF51822 hw revisions (build code) and matching baluns are not updated&quot; which list are you referring to?</p><div style="clear:both;"></div>
