RE: Custom Board with UART and SWD

Hi,

- I don't power the custom board via usb and power it using a battery and connect all other pins to the DK.

This is an ok option.

[quote user=""]- I use RTT instead of UART for communication and data transfer that would take four pins. [/quote]

What kind of communication are you thinking of? The RTT interface is only meant to be used for debugging and should not replace UART as a communication interface in a final product.

- If there is a way to use the swd pins for uart.

No, not really. The pins are dedicated for SWD.

Adding an extra pin header would also solve this issue :)
