STMicroelectronics 32 Bit MCU Microcontroller Board NUCLEO-WL55JC2 with ARM Cortex M4, LoRa, USB 32 MHz NUCLEO-WL55JC2

STMicroelectronics NUCLEO-WL55JC2 is a 32 Bit MCU Microcontroller Board designed for affordable and flexible prototyping with STM32WL Series microcontrollers. It features an ultra-low-power STM32WL55JC dual-core microcontroller combining Arm Cortex M4 and M0+ cores running at 48 MHz in a compact UFBGA73 package.

This board supports a wide range of RF protocols including LoRa®, (G)FSK, (G)MSK, and BPSK modulations in frequency ranges from 150 MHz to 960 MHz, enabling versatile low-power wide-area network applications.

Equipped with 256-Kbyte Flash memory and 64-Kbyte SRAM, it provides sufficient onboard storage for complex embedded applications. Users can interact through 3 user LEDs, 3 user buttons, and a reset push-button for convenient debugging and control.

Connectivity includes a USB Micro-B connector for programming and communication, compatible with ARDUINO Uno V3 shields and additional ST morpho headers granting full access to STM32WL I/Os, enhancing expandability for custom development.

The board integrates an on-board STLINK-V3E debugger and programmer supporting mass storage, virtual COM port, and debug interfaces, eliminating the need for an external probe. It is delivered with an SMA antenna and supports multiple power supply methods including ST-LINK, USB VBUS, or external sources.

Comprehensive free software libraries and examples are available through the STM32CubeWL MCU Package, and it supports popular IDEs like IAR Embedded Workbench, MDK-ARM, and STM32CubeIDE, facilitating rapid development of end nodes across LoRaWAN, Sigfox, wM-Bus, and proprietary protocols.

This microcontroller development tool is suitable for industrial, laboratory, and IoT applications requiring low power, multi-protocol wireless communication and rapid prototyping.

Features STM32WL55JC dual-core microcontroller with Arm Cortex M4/M0+ cores. Supports LPWAN protocols including LoRa® and Sigfox technologies. Includes multiple interface headers including ARDUINO Uno V3 and ST morpho for easy expansion.
