110 Logging is done using the USB-CDC port. See the :zephyr:code-sample:`logging` sample
111 or the :zephyr:code-sample:`usb-cdc-acm-console` sample applications to see how this works.
115 The :zephyr:code-sample:`button` sample lets you test the buttons (switches) and the red LED.
116 The :zephyr:code-sample:`blinky` sample lets you test the red LED.
119 with the :zephyr:code-sample:`led-strip` sample application.
144 Flashing is done by dragging and dropping the built Zephyr UF2-file
147 #. Build the Zephyr kernel and the :zephyr:code-sample:`blinky`
