NUCLEO-WL55JC2 Description

The NUCLEO-WL55JC2 from STMicroelectronics is a versatile NUCLEO-64 development board designed for rapid prototyping of LoRa®-enabled IoT applications. Centered around the STM32WL55JC dual-core microcontroller, it integrates a sub-GHz transceiver operating in the 433MHz to 510MHz frequency range, supporting LoRa®, (G)FSK, (G)MSK, and BPSK modulation schemes. Compliant with ROHS3 and REACH standards, this board is ideal for developers seeking a compact, certified platform for low-power, long-range wireless communication.

NUCLEO-WL55JC2 Features

• Dual-Core STM32WL55JC: Combines an Arm® Cortex®-M4 (application core) and Cortex®-M0+ (radio control core) for efficient processing and RF management.
• Integrated LoRa® Transceiver: Eliminates the need for external RF modules, reducing BOM cost and complexity.
• Frequency Flexibility: Operates across 433MHz, 868MHz, and 915MHz bands (region-specific variants available).
• Arduino™ and ST Morpho Headers: Enables seamless expansion with shields and custom peripherals.
• Ultra-Low Power Design: Optimized for battery-powered LPWAN applications with multiple low-power modes.
• Certified Compliance: ECCN 5A992C, ROHS3, and REACH Unaffected for global deployment.

NUCLEO-WL55JC2 Applications

• Smart Agriculture: Remote sensor nodes for soil monitoring or livestock tracking.
• Industrial IoT: Asset tracking, predictive maintenance, and warehouse automation.
• Smart Cities: LoRaWAN®-based street lighting, waste management, and environmental monitoring.
• Utility Metering: Secure, long-range communication for gas/water/electricity metering.

Conclusion of NUCLEO-WL55JC2

The NUCLEO-WL55JC2 stands out as a highly integrated, cost-effective solution for LoRa®-based designs, combining STM32’s processing power with robust RF performance.
