| Overview |
| ******** |
| |
| The `DFRobot Beetle RP2040`_ board is based on the RP2040 |
| microcontroller from Raspberry Pi Ltd. The board has |
| a USB type C connector, and uses a large pad design. |

| Programming and Debugging |
| ************************* |
| |
| .. zephyr:board-supported-runners:: |
| |
| The DFRobot Beetle RP2040 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`. |
