[Puissance de transmission]：22/13 dBm
[Distance de communication]：5,6/2,6 km
[Introduction]：E80-900M2213S est un module sans fil SPI matériel SMD LoRa double bande développé indépendamment sur la base de la puce LoRa Connect™ LR1121 de SEMTECH pour une connectivité globale multibande. La puissance de transmission est respectivement de 22 dBm et 13 dBm. Le module intègre un oscillateur à cristal à dérive basse température de haute précision de 48 MHz de qualité industrielle. Le LR1121 est l'émetteur-récepteur LoRa à très faible consommation de troisième génération de SEMTECH. Il fournit des communications multibandes LoRa et à spectre étalé à sauts de fréquence longue portée (LR-FHSS) basées sur les bandes ISM sub-GHz et 2,4 GHz, ainsi qu'une connectivité par satellite en bande S. Tout en restant configurable pour répondre aux différents besoins applicatifs et protocoles propriétaires.

Note:
1. The "32k_P/DIO11" and "32k_N/DIO10" pins of the LR1121 radio frequency chip inside the wireless module are connected to the 32.768k crystal oscillator;
2. The "XTA", "XTB" and "VTCXO" pins of the LR1121 radio frequency chip inside the wireless module have been connected to the 32M active crystal oscillator;
3. The "DIO5/RFSW0" and "DIO6/RFSW1" pins of the LR1121 radio frequency chip inside the wireless module are connected to the radio frequency switch to control "Sub-1GHz" and "2.4GHz" radio frequency transceiver. Since the control state of the RF switch is different from the default control state of SEMTECH official SDK, please pay attention to the distinction. For details, please refer to SEMTECH official original SDK or Ebyte custom SDK.
