All-in-one Bluetooth stereo audio module with integrated amplifier and battery charger. A2DP/AVRCP compliant, it allows wireless streaming from any Bluetooth device to a 4-32Ω speaker.
The BLK-MD-SPK-B (BT-Speaker) module is an all-in-one solution for adding Bluetooth stereo audio to your projects. Based on the Bluetooth V2.0 + EDR specification, it integrates an audio decoder, a power amplifier, and a lithium battery charging circuit. It receives A2DP audio streams from smartphones or PCs and provides a complete user interface with 5 control buttons (power, play/pause, volume, next) and status LEDs.
The audio output can directly drive a 4Ω to 32Ω speaker (up to 40mW) without a DC-blocking capacitor. The module also features EEPROM memory for parameter storage and supports automatic reconnection.
