[Introduction]：EWM104-BT5125 (I2S) is a high-performance, low-power, cost-effective BLE5.1 Bluetooth audio module launched by Ebyte. The main control uses Qualcomm's QCC5125 chip to provide the module with a system with on-chip Bluetooth, audio and programmable application processors. It includes high-performance analog and digital audio codecs, class AB and class D headphone drivers, advanced power management, flexible interface protocols and programmable input/output (PIO).
| Main parameters | performance | Remark | |||
