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.
RAK3172 STM32WLE5CC Module with LPWAN single-core Cortex®-M4 at 48 MHz
256-Kbyte Flash memory and 64-Kbyte SRAM
RF transceiver LoRa® modulations
Hardware encryption AES256-bit and a True random number generator

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
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.
.. code-block:: console
Hello World! rak3172/stm32wle5xx
