STMicroelectronics’ long-range wireless and ultra-low-power devices embed a powerful ultra-low-power LPWAN-compliant radio solution
STMicroelectronics’ STM32WLE5/E4xx long-range wireless and ultra-low-power devices embed a powerful ultra-low-power LPWAN-compliant radio solution, enabling the LoRa® (available in STM32WLx5xx only), (G)FSK, (G)MSK, and BPSK modulations. These MCUs are compatible with standardized or proprietary protocols such as LoRaWAN®, Sigfox, W-MBUS, and more (fully open wireless system on chip).
