It s possible to do serial connection through the soft !!en-USTelligent Community 13Wed, 22 Nov 2017 09:07:25 GMThttps://devzone.nordicsemi.com/thread/107227?ContentTypeID=1Wed, 22 Nov 2017 09:07:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:db296675-7cb4-44ee-900a-e8feeac52ac4omar <p>Thank you for your help !</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/107226?ContentTypeID=1Mon, 06 Nov 2017 17:51:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:499ae2d8-2ff1-4992-af36-fef583b340edSigurd<p>As shown <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/abs_max_ratings.html?cp=2_1_0_4#abs_max_ratings">here</a>, the max is VDD + 0.3 V, and max VDD is 3.9V. Recommended VDD is between 1.7V and 3.6V.</p> <p>In order to use 5V for UART, you will need to use some <a href="https://learn.sparkfun.com/tutorials/bi-directional-logic-level-converter-hookup-guide">level shifters</a>. Using 5V directly on the nRF-Pin is not possible.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/107225?ContentTypeID=1Mon, 06 Nov 2017 15:05:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:88e57cac-8994-4aa6-96bc-a847807f4d78omar <p>Yes, i make a custom board without using any of PCA. whath i mean that it&#39;s posible that the NRF pin 10 and 8 support uart connection with +5 V level !!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/107224?ContentTypeID=1Wed, 01 Nov 2017 10:13:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ca80deb0-6682-473e-96ea-89b568740f8dSigurd<p>Hi,</p> <p>You can use the UART on pin 8 and 10.</p> <ul> <li>What do you mean by &quot;rooted a board with NRF52832 SOC without PCA&quot; ?</li> <li>You have made a custom board?</li> </ul><div style="clear:both;"></div>
