+Overview
+********
+
+The `Adafruit Feather Adalogger RP2040`_ board is based on the RP2040
+microcontroller from Raspberry Pi Ltd. The board has a MicroSD-card socket
+for storing data, and a Stemma QT connector for easy sensor usage.
+It is compatible with the Feather board form factor, and has
+a USB type C connector.

+
+
+Programming and Debugging
+*************************
+
+.. zephyr:board-supported-runners::
+
+The Adafruit Feather RP2040 Adalogger board does not expose
+the SWDIO and SWCLK pins, so programming must be done via the USB
+port. Press and hold the BOOT button, and then press the RST button,
+and the device will appear as a USB mass storage unit.
+Building your application will result in a :file:`build/zephyr/zephyr.uf2` file.
+Drag and drop the file to the USB mass storage unit, and the board
+will be reprogrammed.
+
+For more details on programming RP2040-based boards, see
+:ref:`rpi_pico_programming_and_debugging`.
+
+
+Flashing
+========
+
+To run the :zephyr:code-sample:`blinky` sample:
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/basic/blinky/
+   :board: adafruit_feather_adalogger_rp2040
+   :goals: build flash
+
+Try also the :zephyr:code-sample:`led-strip`, :zephyr:code-sample:`input-dump`,
+:zephyr:code-sample:`fs`, :zephyr:code-sample:`usb-cdc-acm-console` and
+:zephyr:code-sample:`adc_dt` samples.
