描述
1. Bluetooth 5.0 version provides higher transmission efficiency and longer transmission distance.
2. Size heat sink ensures efficient heat dissipation.
3. Potentiometer allows volume adjustment with an on/off switch for easy control, ideal for DIY speaker projects. If using a metal enclosure, ensure the Bluetooth antenna is extended.
4. Copper DC connector is used to handle high current with minimal heat generation.
5. Equipped with 4x 470uF capacitors to ensure stable power storage and continuous power supply, supporting consistent audio performance.
6. DC power input with cable allows compatibility with the product’s power interface. Connection is possible even without a dedicated DC adapter or battery.
Adaptation Supply Voltage: 5-24V (compatible with 9V/12V/15V/18V/24V adapters; higher voltage recommended for optimal performance)
