[Introduction]：E04-400M16S est un module émetteur-récepteur sans fil haute performance à très faible consommation. Il s'agit d'un module émetteur-récepteur et émetteur-récepteur sans fil de type patch de très petite taille développé indépendamment sur la base de la puce S2-LPQTR de STMicroelectronics. Il fonctionne dans le 433M/470M bande de fréquences et a une puissance de transmission maximale de 16 dBm. Puisque ce module est du matériel pur SPI
