Hi Peter,

We don't have any samples that explains ONLY setting up UART, as our samples often illustrates multiple functionalities. But our nRF Connect SDK Fundamentals course regarding UART topic which you may find at our academy pages explains how the UART driver works and how to customize the UART in device tree file. This together topic 2 and topic 3 which gives you insight in how the devicetree and configuration files will allow you to enable all 4 UARTS.

Additional resources is the central uart and peripheral uart samples that illustrates how two devices uses the NUS Client to send data back and forth between a UART connection and a Bluetooth® LE connection, emulating a serial port over Bluetooth LE.

Let me know if this clarifies things for you,

Kind regards
Andreas
