[Introduction]:E22-230T30E est une nouvelle génération de module à spectre étalé sans fil LoRa, qui est un module de port série sans fil basé sur la solution LoRa de SEMTECH. Il dispose d'une variété de méthodes de transmission, fonctionne dans la bande de fréquences 220,125-236,125 MHz, est compatible avec les tensions des ports IO 3,3 V et 5 V, utilise un boîtier standard MINI PCI-e et dispose d'options d'interface de communication UART, RS485, RS232 et USB. , pratique à développer et à utiliser pour les utilisateurs. Adoptant une nouvelle génération de technologie à spectre étalé LoRa, cette solution a une distance de transmission plus longue et une vitesse plus rapide ; prend en charge le réveil aérien, la configuration sans fil, la surveillance de l'opérateur, le relais automatique, les boutons de communication et d'autres fonctions, prend en charge le réglage de la longueur des paquets de données et peut fournir services de développement de la personnalité.
Pin No. | Item | Direction | Description |
