[Introduction]：Le module E104-BT41SX est un module esclave Bluetooth série-bimode basé sur Bluetooth 5.4. Il prend en charge les protocoles SPP et BLE, fonctionne dans la bande de fréquence 2,4 GHz et permet de basculer entre BLE et Bluetooth classique. Sa puissance d'émission maximale est de 8 dBm et la configuration des commandes AT simplifie et accélère son utilisation. Ce module permet la transmission de données sans fil entre des périphériques série classiques d'entrée de gamme et des périphériques contrôlés par microcontrôleur. C'est un module de transmission de données économique, simple d'utilisation et fiable.
