nRF52840 Dev Kit UART Example uses default 115200 baud on low-speed <10kHz pins?

[tb32]

The nRF52840 UART example uses pins 1.13 and 1.14 for the TX and RX pins on the Dev Kit (uart_pca10056) and has a default baud rate of 115200, but the 1.13 and 1.14 pins are specified as low speed only. Is this a mistake in the example or the datasheet?

Hi

You're absolutely correct. I would suggest editing this example to use some other GPIOs for UART connectivity in order to avoid any performance degradation. I will report this internally, so this might be fixed in a future release. Thank you for sharing your discovery with us!

Best regards,
