JDY-62A Dual Channel Bluetooth Audio Stereo Module

JDY-62A Dual Channel Bluetooth 5.0 Audio Stereo Module is an ultra-compact, high-fidelity wireless audio receiver explicitly designed to add Bluetooth streaming capabilities to any wired audio system. Acting as a dedicated audio bridge, this miniature module flawlessly receives wireless Bluetooth signals and decodes them into a clean, unamplified left and right analog stereo output. Consequently, hobbyists overwhelmingly prefer this receiver for upgrading vintage analog stereos, assembling DIY Bluetooth headphones, or adding wireless connectivity to custom Arduino speaker projects. The board operates efficiently on a wide 3.6V to 5V DC supply, making it perfectly compatible with standard USB power or a single lithium-ion battery cell. Furthermore, its onboard PCB antenna provides a robust, low-latency Bluetooth 5.0 connection up to 15 meters without requiring external aerials.

Key Features:

• Bluetooth 5.0 Connectivity: Guarantees a stable, high-speed, and low-latency audio transmission, therefore preventing frustrating lip-sync issues during video playback.
• Pure Stereo Output: Delivers true dual-channel audio (Left and Right) directly to headphones or the line-in stage of an external power amplifier.
• Microscopic Footprint: The astonishingly small PCB layout allows it to easily hide inside existing headphone shells, car dashboard panels, or tight enclosures.
• Auto-Connect Functionality: Intelligently remembers paired devices and automatically reconnects upon powering up, consequently eliminating repetitive pairing processes.
• Low Power Sleep Mode: Automatically enters a power-saving standby state after 10 minutes of inactivity to preserve battery life in portable applications.
