BT5.0 Audio PRO Decoder Module

BT5.0 Audio PRO Decoder Module/Mini Bluetooth 5.0 Decoder Module/Wireless Stereo Music Amplifier Module

Description

BT5.0 Audio PRO continues the excellent basic functions of M28 (long-distance transmission, Bluetooth 5.0 backward compatible, lossless sound quality, etc.), and adds more user-friendly performance, as follows:

• Charge while putting:
  This product features a charging and discharging circuit, enabling direct battery charging via USB power while Bluetooth continues to function. It effectively addresses the issue of non-usable products during charging. When powered solely by USB, the flashing red light indicates normal power supply.
  When powered by a separate battery, the yellow light remains steady to show normal battery power; flashing yellow indicates low battery. When both USB and battery are connected, the red light flashes during charging and stays on when fully charged.
• Incoming voice call function:
  Once Bluetooth is connected, enable call audio mode in Bluetooth settings. Use the PLAY/STOP button to answer or end calls. Choose between headset microphone or onboard mic for calls (provided the headset is 4-segment).
  For computer sound card use, tin the pads in corresponding boxes on the module’s back, then connect it to a computer’s USB interface via USB cable to function as a sound card. This routes computer sound output through the module’s audio interface. (This feature is not enabled by default).
