https://devzone.nordicsemi.com/f/nordic-q-a/2/is-it-possible-to-run-the-nrf51822-from-a-5v-supply-directlyHi, the nRF51822 specifies a max voltage limit of 3.6v. Would the device actually operate from a 5v supply albeit with a shortened lifespan? thank youen-USTelligent Community 13Tue, 25 Jun 2013 17:41:07 GMThttps://devzone.nordicsemi.com/thread/3?ContentTypeID=1Tue, 25 Jun 2013 17:41:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f4306012-b314-4158-8a3a-695c3e8e4cc2Marc Nicholas<p>Couple of 1N series diodes in series? ;)</p> <p>-m</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/4?ContentTypeID=1Thu, 30 May 2013 13:15:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:573b4f52-6fbb-4e6e-8c9d-c3b076c821cfOle Morten<p>This is unfortunately not directly possible, as the nRF51822s absolute maximum VDD value is 3.6 V, as given in table 13 in the nRF51822 PS. Permanent, immediate damage may occur if you exceed this.</p><div style="clear:both;"></div>
