Product Overview

NUCLEO-WL55JC1 is a STM32WL nucleo-64 board. It provides an affordable and flexible way for users to try out new concepts and build prototypes with the STM32WL series microcontroller, choosing from the various combinations of performance, power consumption, and features. The ARDUINO® Uno V3 connectivity support and the ST morpho headers provides an easy means of expanding the functionality of the STM32WL nucleo open development platform with a wide choice of specialized shields. The STM32WL nucleo-64 board does not require any separate probe as it integrates the STLINK-V3E debugger and programmer. It is suitable for rapid prototyping of end nodes based on LoRaWAN, Sigfox, wM-Bus, and many other proprietary protocols. It has support of a wide choice of integrated development environments (IDEs) including IAR Embedded Workbench®, MDK-ARM, and STM32CubeIDE.
