[Introducción]:El E04-400M20S es un módulo de comunicación inalámbrica SoC basado en la solución de chip STM32WL33 recientemente lanzada por STMicroelectronics. El módulo inalámbrico tiene las características de larga distancia de comunicación, bajo consumo de energía en modo de espera, fuerte capacidad antiinterferencias, abundantes recursos de interfaz, fuerte capacidad de procesamiento y tamaño pequeño. También es adecuado para módulos inalámbricos de parche de banda de frecuencia 433/470, utilizando osciladores de cristal de 32,768 KHz y 48 MHz de alta precisión de grado industrial para garantizar el funcionamiento estable del módulo. Este módulo inalámbrico requiere un desarrollo secundario por parte del usuario y puede usarse ampliamente en la industria de Internet de las cosas.
