ماژول بلوتوث صوتی مدل JDY-61

The Bluetooth audio module requires very high power, otherwise, it will affect the sound quality. The power supply must be provided if the LC filter circuit is a switching power supply.

PCB size: 23 x 15 x 2.4mm

Pin pitch: 2.54mm
Stereo amplifier

Common problem:

1, search less than blue:

The power line, usually caused by power interference, must be connected to the LC filter circuit.

2, Whether to support 3.7V power supply:

The module is powered by 5V by default. You can replace the diode in the JDY-61 module with 0805 or resistor, or use wire for a short circuit, so you can use a lithium battery

3, Bluetooth signal is very weak

Do not route or turn off the copper under the antenna of the Bluetooth module. There should be no metal shields around the antenna.

4, the current sound is too loud

It is recommended that the wiring of the power amplifier is not too long and that the Bluetooth port and power port are disconnected, usually caused by power supply interface interference.

VCC: voltage range 4.2V to 5V, in particular, can not exceed 5V power supply
GND: Power
L: Left channel output
R: Right channel output
MUTE: muted the sound
KC: Empty Pin
