We are about to build a prototype for a 2022 product, which will need 4x UART.

Is there an ETA for this fixed revision?

Hi, I got a nRF5340 PDK. Does this applies to PDK or it is for other particular board? Looking at info center there is separate tab for PDK. can I use 4 UART on PDK or not ?

Thanks for the quick reply and for the good news (I really wanted the answer to be 4 :) )

Hi,

[quote user=""]So what is the actual maximum number of UARTs supported by the application core? Thank you.[/quote]

Thank you for reporting this. The correct number is 4. But, on the nRF5340 Engineering A only 2 of them are functional, see this errata. This will be fixed in a upcoming IC revision of the nRF5340.
