Now I wanted to re-order a few hundred pieces the seller told me that they have &quot;C series&quot;. What is NRF905 C series? I thought it is just a letter for indicating the production site. Is it somethingen-USTelligent Community 13Wed, 19 Aug 2015 13:29:59 GMThttps://devzone.nordicsemi.com/thread/32152?ContentTypeID=1Wed, 19 Aug 2015 13:29:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7cf421c0-8d6a-467c-bcdd-bf301e22ed3aStefan Birnir Sverrisson<p>Hi</p> <p>I suspect the same as you, i.e. that the seller is referring to the build code. There is no C series of nRF905, just build code B or C. The build code you currently have is apparently C, so if he has the same build code, he should be providing you with the same chip. <a href="https://www.nordicsemi.com/eng/nordic/Products/nRF905/PCN-008/8076">Here is the PCN</a> from build code B to C</p><div style="clear:both;"></div>
