LoRa-enabled boards support world’s first LoRa SoC

15-01-2021 | Mouser Electronics | Subs & Systems

Mouser now stocks the STMicroelectronics STM32WL Nucleo-64 boards, based on the new STM32WL Series microcontroller. The device is claimed to be the world’s first wireless microcontroller to integrate a LoRa transceiver on its silicon die, satisfying the demands of a wide range of LPWAN wireless applications in industrial and consumer IoT markets.


The boards offer an affordable and flexible way for design engineers to test out new sub-GHz wireless communications concepts and create prototypes with the new series wireless microcontroller, selecting from the different combinations of performance, power consumption, and features. The boards comprise support for both Arduino Uno headers and ST morpho headers to offer an easy way of extending the functionality of the platform with an extensive choice of specialised shields. The boards also combine the STLINK-V3E debugger and programmer, eliminating the necessity for a separate probe.


The onboard STM32WL55JC microcontroller includes two 32-bit Arm Cortex-M4/M0+ cores with 256Kbytes of flash memory and 64Kbytes of SRAM. The device’s specifically engineered radio provides two power outputs — one up to 15dBm and the other up to 22dBm — and supports LoRa, (G)FSK, (G)MSK, and BPSK modulations. The NUCLEO-WL55JC1 supports the high-frequency band from 865MHz to 928 MHz used in the Americas and Europe, while the NUCLEO-WL55JC2 supports the low-frequency band from 433MHz to 510MHz employed in Asia, enabling design engineers worldwide to utilise the STM32WL in their designs.






The STM32WL Nucleo-64 boards come with the STM32WL comprehensive software HAL library and various packaged software examples offered with the STM32CubeWL MCU Package.
