STM32WL5x 32-Bit Wireless Long-Range MCUs

STMicroelectronics' STM32WL55/54xx long-range wireless and ultra-low-power devices embed a powerful ultra-low-power LPWAN-compliant radio solution, enabling modulations LoRa® (available in STM32WLx5xx only), (G)FSK, (G)MSK, and BPSK. These MCUs are compatible with standardized or proprietary protocols such as LoRaWAN®, Sigfox, W-MBUS, and others (fully open wireless system on chip).

Compatible with standardized or proprietary protocols such as LoRaWAN, Sigfox, W-MBUS and more (fully open wireless System-on-Chip).
