JDY‑62A Bluetooth Audio Module
📌
Product Overview JDY‑62A is a compact Bluetooth stereo audio receiving module. It adopts an integrated audio Bluetooth chip, supports high‑fidelity stereo audio output with left and right channel analog audio signal pins. The module defaults to 5V power supply, and it can be modified to work with 3.7V lithium battery by simple hardware adjustment. Equipped with mute control pin, floating function pin and built‑in PCB antenna for stable wireless connection. It is widely used for DIY Bluetooth speakers, audio amplifier transformation, car audio modification and various custom wireless audio projects.

Important Notes
- The standard version is powered by DC 4.2‑5V, the supply voltage must not exceed 5V
- It is recommended to add an LC filter circuit on the power supply terminal to reduce power interference and avoid audio noise or Bluetooth search failure
- Do not lay wires or copper under the onboard antenna area, keep away from metal shielding to guarantee receiving sensitivity
- Separate the Bluetooth module ground and power amplifier ground to reduce current noise
- For 3.7V lithium battery power supply, replace the surface‑mount diode with a 0R resistor or short‑circuit the pad manually
