Product overview
Description
The main objective of the STM32WL3x microcontroller reference designs is to recommend a layout and associated BOM for dedicated applications (these boards are not for sale).
These reference designs can be manufactured from files available for download from the www.st.com website. The access to all GPIOs allows the prototyping of a complete application.
Sensitive layout parts can be extracted and pasted in any user board design with the same PCB characteristics and feature set.
The STM32WL3x microcontroller reference designs are provided with the STM32WL3x comprehensive software HAL library. The STM32CubeWL3 MCU Package contains many software examples developed with the STM32WL3x Nucleo-64 boards (NUCLEO-WL33CC1 and NUCLEO-WL33CC2). These examples can be easily adapted for the STM32WL3x microcontroller reference designs.
Using the reference designs to design the user application helps to get the right RF performance and to pass certification.
