Simplified development board to easily prototype end nodes based on LoRaWAN, Sigfox, W-MBus, mioty and many other proprietary protocols
A Nucleo-64 development board, the NUCLEO-WL55JC allows developers to try out new ideas and to quickly create prototypes based on the multi-protocol LPWAN STM32WL MCU.
The telecommunication service provider Orange has selected the board as key connectivity solution in their IoT Journey ecosystem.
Designers using the NUCLEO-WL55JC can also benefit from the Microsoft® Azure RTOS thanks to its associated software expansion package.

The STM32WL55JC microcontroller is a long-range wireless and ultra-low-power device that integrates both a general-purpose microcontroller and a sub-GHz radio on the same chip.
Built on Arm® Cortex®‐M4 and Cortex®-M0+ cores (single- and dual-core architectures available), the STM32WL55JC microcontroller supports multiple modulations, such as LoRa®, (G)FSK, (G)MSK, BPSK, to ensure flexibility in wireless applications with LoRaWAN®, Sigfox, W-MBUS, mioty® or any other suitable protocol in a fully open way.
The STM32CubeWL MCU Package is composed of the STM32Cube hardware abstraction layer (HAL) and the low-layer (LL) APIs, plus a consistent set of middleware components such as FatFS, STM32 Secure Engine, KMS, mbed Crypto and FreeRTOS™, plus LoRaWAN® and Sigfox™ stacks, and sub-GHz PHY connectivity services.
The X-CUBE-AZRTOS-WL software package brings together essential components that simplify the design of reliable and energy-efficient smart objects. It allows designers to benefit from Azure RTOS pre-certifications for safety and security applications.
