Mouser now stocks the STMicroelectronics STM32WL Nucleo-64 boards, based on the new STM32WL Series microcontroller. The board is claimed to be the world's first wireless microcontroller to integrate a LoRa transceiver on its silicon die, satisfying the demands of an extensive range of LPWAN wireless applications in industrial and consumer IoT markets.
The NUCLEO-WL55JC1 and NUCLEO-WL55JC2 boards offer a cost-effective and compliant way for design engineers to test out new sub-GHz wireless communications concepts and create prototypes with the series wireless microcontroller, picking from the different blends of performance, power consumption, and features. The boards comprise support for both Arduino Uno headers and ST morpho headers to provide an easy way of extending the functionality of the open development platform with a wide choice of specialised shields. The boards also combine the STLINK-V3E debugger and programmer, eliminating the requirement for a separate probe.
The onboard STM32WL55JC microcontroller includes two 32-bit Arm Cortex-M4/M0+ cores with 256kB of flash memory and 64kB of SRAM. The device's specially engineered radio provides two power outputs – one up to 15dBm and the other up to 22 dBm – and supports LoRa, (G)FSK, (G)MSK, and BPSK modulations. The microcontroller supports the high-frequency band from 865MHz to 928MHz used in the Americas and Europe, while the NUCLEO-WL55JC2 supports the low-frequency band from 433MHz to 510MHz used in Asia, enabling design engineers worldwide to utilise the STM32WL in their designs.
The boards come with the STM32WL comprehensive software HAL library and numerous packaged software examples available with the STM32CubeWL MCU package.
