STMicroelectronics NUCLEO-WL55JC Development Board

Provides ready-made platform for evaluation of LPWAN SoC

STMicroelectronics has introduced the NUCLEO-WL55JC board, which provides a time-saving platform for the development of connected industrial and IoT applications based on the STM32WL55/54 series of wireless microcontrollers. This Nucleo board is also suitable for the development of applications which are intended to be based on the STM32WLE5/E4 MCUs.

The STM32WL55 is a System-on-Chip (SoC) which combines a dual-core MCU with a sub-1GHz radio to provide Low-Power Wide-Area Networking (LPWAN) capability. The STM32WL55 implements LoRa^® radio communications, as well as supporting the (G)FSK, (G)MSK and BPSK long-range radio modulation schemes. Featuring a similar hardware specification, the STM32WL54 SoC supports (G)FSK, (G)MSK and BPSK modulation and not the LoRa protocol.

By integrating a full-featured MCU based on dual Arm^® Cortex^®-M4 and Cortex-M0+ cores and a sub-1GHz radio into a single chip, ST enables developers of connected industrial and IoT applications to simplify their board design and assembly process, and to reduce bill-of-materials costs. The SoC’s Cortex-M0+ core performs various security services including secure firmware updating, secure firmware installation and management of secure keys. Application code runs on the Cortex-M4 core.

The NUCLEO-WL55JC board features Arduino^® Uno V3 connectivity support and ST morpho headers to provide an easy means of expanding the functionality of the STM32WL Nucleo open development platform with a wide choice of specialized shields. This Nucleo board does not require a discrete probe as it includes an integrated STLINK-V3E debugger and programmer.

The STMicroelectronics board is supplied with the comprehensive STM32WL software library and various packaged software examples available with the STM32CubeWL MCU package. It supports a wide choice of integrated development environments including IAR Embedded Workbench^®, MDK-ARM, and STM32CubeIDE.

The Nucleo board is available in two versions:
