https://devzone.nordicsemi.com/f/nordic-q-a/50760/nrf52480-4-uartHello I need to connect 4 UART devices to the nrf52480 1 needs to be with CTS and RTS, the other 3 just rx, tx , gnd can that be done ?en-USTelligent Community 13Thu, 08 Aug 2019 00:00:32 GMThttps://devzone.nordicsemi.com/thread/202933?ContentTypeID=1Thu, 08 Aug 2019 00:00:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a7613c6d-a997-4081-bb33-660bf12d7417RK<p>No not really. The 52840 only has 2 UART peripherals. You can try bitbanging but that never works properly with the softdevice. If you only need to use one device at a time you could keep switching the pin selection in the UARTs around in software but that doesn&#39;t help you at all if you need to access all the devices constantly. Or you could use an external device which provides 4 UARTs on a SPI interface, MaxLinear makes them for instance, cost about $10</p><div style="clear:both;"></div>
