nrf52480 4 uart

[deadpoolcode]

Hello

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 ?

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'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
