EoRa-HUB-900TB Solution de puce LR1121, carte de développement de module LoRa double fréquence, projet open source de hub à un canal
[Interface]：Type-C
[Taille]：27 x 54 mm
[Introduction]：EoRa-HUB-900TB est une carte de développement de module LoRa double bande conçue et produite par Ebyte. Il se compose de modules de la série E80 (modules LR1121) et de modules WiFi de la série ESP32-S3. Il dispose de nombreuses broches externes et d'un écran OLED de 0,96 pouce et propose trois méthodes de communication : LoRa, Wi-Fi et Bluetooth. L'appareil a été largement utilisé dans le domaine du développement de l'IoT et de la communication longue distance, en particulier dans l'application de la technologie SEMTECH One-ChannelHub (passerelle monocanal LoRaWAN), qui a été reconnue par la majorité des utilisateurs.
