The V2 Bluetooth Audio Module CA-6928 receives wireless audio from phones, laptops, and tablets over Bluetooth V2 protocol. It runs on 3.7V to 5V DC, so a standard USB power bank or 18650 Li-ion cell powers it without any regulator. Output power sits at 3 watts, enough to drive a small 4-ohm or 8-ohm speaker at room volume. The bluetooth audio module connects to a speaker directly without any external amplifier board.
One limitation worth knowing — Bluetooth V2 does not support aptX or AAC audio codecs. Audio quality is acceptable for casual listening but not for high-fidelity setups. The CA-6928 bluetooth module pairs automatically with the last connected device on power-up, which saves time in fixed installations. Connectivity range reaches up to 10 meters in open space.
The 5v bluetooth audio receiver module is widely used by Indian hobbyists for retrofitting wired speaker systems and building portable Bluetooth speakers for workshops. The ca 6928 bluetooth module requires no drivers and no code — it works the moment power is connected.
StemVolt provides this sensor with trusted quality, ensuring reliable performance and easy usability.
