[Introduction]：L'EWM104-BT5125 (I2S) est un module audio Bluetooth BLE5.1 hautes performances, basse consommation et économique, lancé par Ebyte. Le contrôle principal utilise la puce QCC5125 de Qualcomm pour doter le module d'un système intégrant des processeurs Bluetooth, audio et d'applications programmables. Il intègre des codecs audio analogiques et numériques hautes performances, des pilotes de casque de classe AB et de classe D, une gestion avancée de l'alimentation, des protocoles d'interface flexibles et des entrées/sorties programmables (PIO).
| Main parameters | performance | Remark | |||
