Bluetooth Audio Receiver Module 3.3Vdc CA-6928

Bluetooth Audio Receiver Module 3.3V DC – CA-6928

The CA-6928 Bluetooth Audio Receiver Module is a compact and efficient wireless audio solution designed to add Bluetooth functionality to amplifiers, speakers, and DIY audio systems. Built around the CA-6928 Bluetooth audio receiver module, this module enables seamless audio streaming from smartphones, tablets, and other Bluetooth-enabled devices.

Operating within a low voltage range of 3.3V to 5V DC, the CA-6928 is ideal for embedded systems and portable electronics. It uses Bluetooth technology (commonly version 4.1 or 5.0 depending on the variant), providing stable wireless connectivity with a typical range of up to 10 meters.

This module outputs stereo audio signals (L/R channels) that can be connected directly to an external amplifier or active speakers. Some versions also include a small onboard amplifier (up to 2×3W), allowing direct connection to speakers without additional circuitry.

Its ultra-compact size (around 24 × 15 mm) and low power consumption make it perfect for space-constrained projects. The module also features LED indicators for pairing and connection status, making it user-friendly and easy to integrate.

Whether you're upgrading a traditional speaker system to wireless, building a DIY Bluetooth speaker, or integrating audio streaming into an embedded system, the CA-6928 module offers a simple and cost-effective solution.
