The CA-8469 Bluetooth Audio Amplifier Module is a high-performance, compact circuit board designed to convert passive speakers into a modern wireless sound system. At Electrapac, we recommend this board for desktop speaker builds and DIY "Boombox" projects due to its excellent signal stability and integrated power management.

Product Overview

The CA-8469 is a dual-channel (stereo) digital amplifier that combines a Bluetooth 5.0 receiver with a high-efficiency Class D amplification stage. It is specifically engineered to deliver "Hi-Fi" quality audio while maintaining a small footprint, making it perfect for fitting into tight desktop enclosures or portable speaker cases.
