[Introduction]:Le produit E34-2G4H27SX est un module de transmission de données sans fil développé par Ebyte. Il fonctionne dans la bande de fréquences 2,4-2,518 GHz, semi-duplex, sortie de niveau TTL, compatible avec les tensions des ports IO 3,3 V et 5 V, et utilise le port série pour. transmission et réception de données. Le module sans fil a une fonction de saut de fréquence automatique, une forte capacité anti-interférence, un taux de transmission élevé et un faible retard.
