Tools & software
NUCLEO-WL33CC1
STM32 Nucleo-64 development board with STM32WL33CC MCU (868/915MHz), supports Arduino and ST morpho connectivity
The STM32WL3x Nucleo-64 boards based on the MB1801 mezzanine board and MB2029 MCU RF board (NUCLEO-WL33CC1 and NUCLEO-WL33CC2 order codes) embed the STM32WL33CCV6 sub-GHz application processor. This high‑performance and low‑power application processor can operate in 433, 868, and 915 MHz bands.
The ARDUINO® Uno V3 connectivity support and the ST morpho headers provide an easy means of expanding the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields.
STM32CubeWL3 - STM32Cube MCU Package for STM32WL3 series (HAL, Low-Layer APIs and CMSIS, File system, RTOS, LPWAN stack - and examples running on ST boards)
STM32Cube is an STMicroelectronics original initiative to improve designer productivity significantly by reducing development effort, time, and cost. STM32Cube covers the whole STM32 portfolio.
STM32Cube includes STM32CubeMX, a graphical software configuration tool that allows the generation of C initialization code using graphical wizards.
It also comprises the STM32CubeWL3 MCU Package, composed of the STM32Cube hardware abstraction layer (HAL) and the low-layer (LL) APIs, a consistent set of middleware components such as Sigfox™ binary libraries with a complete set of APIs, wM-Bus middleware implementing the physical and data link layers, FreeRTOS™ kernel, and FatFS generic file system module.
STM32CubeWiSEcg - Graphical user interface to graphically build STM32WL3x transceiver actions flowgraph
The STM32CubeWiSE-RadioCodeGenerator (STM32CubeWiSEcg) is a graphical application to create flow graphs for the STM32WL3x MRSUBG embedded sequencer, a state machine-like mechanism for the autonomous management of RF transfers.
The flow graphs specify the transceiver actions to be executed under various conditions, utilizing the MRSUBG driver.
STM32CubeWiSE-RadioCodeGenerator assists developers in creating source code for the STM32WL3x MRSUBG embedded sequencer by providing a graphical interface.
A portfolio of 7 RF integrated passive devices (IPDs), MLPF-WL-0xD3 RF IPDs, is available and ready to be used as STM32WL3 companion devices. RF IPDs, integrating into a tiny footprint the RF BoM of harmonic filters and impedance matching, can be used to speed up RF design and time-to-market.
