E22P-915M30S Module émetteur-récepteur RF SX1262 915 MHz Oscillateur à cristal compensé en température actif de haute précision 32 MHz
[Solution de puce]：SX1262
[Fréquence]：915 MHz
[Puissance d’émission]：30 dBm
[Distance de communication]：12 km
[Size]：38,5 x 24 mm
[Poids]：5,1 ± 0,1 g
[Introduction]：Les modules de la série E22P-915M30S 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 902-928 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.
