I have usually managed to let it work on 3.1V also, but 3.0V usually fails, so that seems to be the boundary. It might work if you install a fresh 3V coin cell battery on the module, which might be a little over 3 volts to begin with at least.</p> <p>For connecting the device with the programmer, see also <a href="https://devzone.nordicsemi.com/question/3863/pinout-of-p3-swd-on-pca10004-and-pca10005/">this thread</a>.</p> <p>Programmers from Segger that accept down to 1.8V on the target <a href="http://segger.com/flasher-arm.html">(1)</a> <a href="http://segger.com/j-trace-for-cortex-m.html">(2)</a>. The former is production qualified.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/36202?ContentTypeID=1Sat, 17 Oct 2015 15:03:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a9302d13-9a25-43f8-a904-8684f90ca24eHamza<p>I tried this as well.. did not help... :(</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/36201?ContentTypeID=1Sat, 17 Oct 2015 11:24:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0dc17606-40cc-4124-b320-f526dc4e1188vineeshvs<p>You can use use Jflash lite</p><div style="clear:both;"></div>
