EoRa-HUB-400TB Carte de développement sans fil LoRa ESP32-S3+LR1121 hub monocanal
[Introduction]：L'EoRa-HUB-400TB est une carte de développement de module LoRa bi-bande conçue et produite par Ebyte, basée sur la puce LR1121. Elle se compose d'un module de la série E80 (module LR1121) et d'un module Wi-Fi de la série ESP32-S3. Dotée de nombreuses broches externes et d'un écran OLED de 0,96 pouce, elle offre trois modes de communication : LoRa, Wi-Fi et Bluetooth. Largement utilisé dans le développement de l'Internet des objets (IoT) et des communications longue distance, notamment pour la technologie SEMTECH One-ChannelHub (passerelle monocanal LoRaWAN), ce dispositif a été plébiscité par de nombreux utilisateurs.
