CA-6928 5V入力と23x15mmサイズダブルデジタル音声増幅器のBluetoothオーディオモジュール

Excellent Bluetooth amplifier module! The sound quality is crystal clear with impressive 90dB SNR. Easy to install and works perfectly with my audio system. The frequency response covers the full range 20Hz-20KHz as advertised. Highly recommend for DIY audio projects!

Great amplifier board! The Bluetooth 5.0 connection is super stable, no dropouts even when I'm 10 meters away. The Sinilink APP control is really convenient, I can adjust volume and switch songs directly from my phone. I used it to build a portable outdoor speaker, and the 100W×2 output is more than enough for backyard parties. Sound is clear with no distortion at high volumes. Installation was straightforward, all ports are clearly labeled. Highly recommend!

Perfect for my DIY project! I built a small bookshelf speaker for my study, and this module is exactly what I needed. The wide DC 8-18V input range is very convenient - I can power it with an old laptop charger. Sound is clear and crisp, no distortion at normal listening levels. It's compact and easy to wire, even for a beginner like me. Great product at a great price, arrived in Australia in 10 days.
