NUCLEO-WL55JC

NUCLEO-WL55JC: the development board to quickly boost your LPWAN application design!

NUCLEO-WL55JC

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.

ST is a Silver Sponsor of the official global LoRaWAN® event in Paris, July 6-7.

Experience the power of the LoRa-enabled STM32WL SoC and meet our experts at our booth to discover exciting new business opportunities!
