[Introduction]:Le E80-900M2212S(LR2021) est un module sans fil LoRa double bande de type patch, utilisant l'interface SPI et développé indépendamment à partir de la puce LR2021, composant IP LoRa® de quatrième génération de SEMTECH. Il offre des puissances d'émission respectives de 22 dBm et 12 dBm. Le module intègre un oscillateur à cristal actif de haute précision de 32 MHz à compensation de température de qualité industrielle et prend en charge les bandes Sub-GHz, 2,4 GHz ISM et les réseaux de communication terrestres et par satellite sous licence en bande S.
