NUCLEO-WL55JC1 STM32WL Nucleo-64 board

Added to your shopping cart

STMicroelectronics STM32WL Nucleo-64 Board (NUCLEO-WL55JC) can be used to try new concepts and build prototypes for LoRa™ applications with the STM32WL Series sub-GHz wireless microcontroller. Choose from combinations of performance, power consumption, and features. Expand the functionality of the STM32WL Nucleo with Arduino® Uno V3 connectivity support and ST morpho headers, and access a wide choice of specialized shields. The STM32WL Nucleo-64 board does not require any separate probe as it integrates the STLINK-V3E debugger and programmer. The STM32WL Nucleo-64 Board is provided with the STM32WL comprehensive software HAL library and various packaged software examples available with the STM32CubeWL MCU Package.

The STMicroelectronics STM32WL Nucleo-64 Board is offered in two variants. The NUCLEO-WL55JC1 is designed to cover the RF frequency range from 865MHz to 928MHz. NUCLEO-WL55JC2 is designed to cover the RF frequency range from 433MHz to 510MHz.
