[Introduction]:Les modules de la série E22P-868M30S sont des modules sans fil LoRa™ à montage en surface, développés indépendamment à partir de la puce RF hautes performances SX1262 de Semtech. Ils fonctionnent dans la bande de fréquences 863,3-873,3 MHz et utilisent un oscillateur à quartz actif à compensation thermique de haute précision et de qualité industrielle. L'ajout d'un module frontal RF (RF FEM) améliore les performances anti-interférences et la portée de communication, creusant ainsi l'écart avec les produits utilisant les méthodes de modulation FSK et GFSK.
