| Overview |
| ******** |
| |
| RAK3172 is a WisDuo LPWAN module which integrating a STM32WLE5CC chip. |
| The breakout board has the RAK3172 as its core and with soldered to the |
| antenna connector. |
| |
| Hardware |
| ******** |
| |
| The breakout board footprint allows RAK3172 stamp module pins to be transferred to 2.54 mm headers. |
| It is designed to easy access to the pins on the board and simplify the evaluation of the RAK3172 |
| module. |
| |

| Supported Features |
| ================== |
| |
| .. zephyr:board-supported-hw:: |
| |
| Programming and Debugging |
| ========================= |
| |
| .. zephyr:board-supported-runners:: |
| |
| The RAK3172 board can be debugged and flashed with an external debug probe connected |
| to the SWD pins. |
| It can also be flashed via `pyOCD`_, but have to install an additional pack to support STM32WL. |
| |
| .. code-block:: console |
| |
| $ pyocd pack --update |
| $ pyocd pack --install stm32wl |
| |
| Flashing an application |
| ----------------------- |
| |
| Connect the board to your host computer and build and flash an application. |
| The sample application :zephyr:code-sample:`hello_world` is used for this example. |
| Build the Zephyr kernel and application, then flash it to the device: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: rak3172 |
| :goals: build flash |
| |
| Run a serial terminal to connect with your board. By default, ``usart1`` is |
| accessible via the USB to TTL converter. |
| |
