https://devzone.nordicsemi.com/f/nordic-q-a/78164/3x-uart-gpio-configurationHi, Actually we are searching for a chip which has more than one UART channel for communication. Can we define more than one UART channel with GPIO configuration? Is it possible to define multiple GPIO as RX TX pins?en-USTelligent Community 13Tue, 03 Aug 2021 13:25:38 GMThttps://devzone.nordicsemi.com/thread/323130?ContentTypeID=1Tue, 03 Aug 2021 13:25:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f53d1520-2480-46fc-bbf3-f7d68ac1f631J&#248;rgen Holmefjord<p>Hi,</p> <p>nRF52832 has only one UART(E) instance. This instance can be moved around to different GPIOs for the TX and RX pins, but it can only be connected to one pin-set at the time.</p> <p>nRF52833 and nRF52840 have <a href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/uarte.html#topic">two UARTE instances</a>, so this is an option if you need more UART instances.</p> <p>nRF5340 have support for <a href="https://infocenter.nordicsemi.com/topic/ps_nrf5340/uarte.html#topic">up to 5 UARTE instances</a> (4 in application core + 1 in network core), but note that these share base address with SPI/TWI instances, so you can only enable one protocol for each instance at a time.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
