nRF5340 IO mapping and connection to nRF9160https://devzone.nordicsemi.com/f/nordic-q-a/61825/nrf5340-io-mapping-and-connection-to-nrf9160I&#39;m working on a new nRF5340 project where this will be the main application processor. The target system will support a large variety of sensors, and we expect to use a very large part of the nRF5340&#39;s IO bus capability, both for digital GPIO, analogen-USTelligent Community 13Thu, 28 May 2020 14:06:33 GMTRE: nRF5340 IO mapping and connection to nRF9160https://devzone.nordicsemi.com/thread/252232?ContentTypeID=1Thu, 28 May 2020 14:06:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:07a63478-421a-4fa5-8541-47dd842522a5borgestrand<p>Thank you</p> <p></p> <p>B&oslash;rge</p><div style="clear:both;"></div>RE: nRF5340 IO mapping and connection to nRF9160https://devzone.nordicsemi.com/thread/252196?ContentTypeID=1Thu, 28 May 2020 13:04:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:16d6c419-ce16-4dd4-9a1b-442e44bf411eMarjeris Romero<p>Hi,<br />&nbsp;<br />Take a look at the<a href="https://infocenter.nordicsemi.com/topic/ps_nrf5340/chapters/pin.html?cp=3_0_0_8_0"> Pin assignments</a> in the Hardware and layout section in the nRF5340 OPS to see the pins you have available for GPIO. Keep in mind that if you are planning to use external 32kHz crystal you cannot use P0.00 and P0.01 as GPIO, the same will apply with all other pins with shared functionality, e.g NFC. <br /><br />You can use all serial interfaces, it will depend on what kind of data you want to send. UART is probably the easiest to implement. </p> <p>Best regards,</p> <p>Marjeris</p><div style="clear:both;"></div>
