JDY-62A bluetooth 5.0 bluetooth stereo module bluetooth audio module audio bluetooth -75543
product detail
The pins can be soldered with pin headers or patches, the pin spacing is 2.54mm, and 2.54 pin headers can be soldered
Pin description:
1. VCC: The voltage range is 4.2 to 5V, especially the power supply cannot exceed 5V
2. GND: power ground
3.L: Left channel output
4.R: Right channel output
5. MUTE: low level when playing music, stop playing and output high level
6.KC: empty pin
Wiring diagram:
The Bluetooth-compatible audio module has very high power requirements, otherwise it will affect the audio quality. The power supply must be added with an LC filter circuit, especially a switching power supply.
Common problem:
1. Bluetooth-compatible cannot be searched:
Generally, it is caused by power interference, and the power line must be added with an LC filter circuit
2. Whether it supports 3.7V power supply:
The module is powered by 5 volts by default. You can replace the upper diode of the JDY-62 module with a 0805 package 0R resistor, or use a short circuit with a wire, so that it can be powered by a lithium battery
Note:
When 3.7V bulk order is required, please indicate 3.7V power supply before placing the order. The default is 5V power supply.
3. The Bluetooth-compatible signal is too weak
Do not wire or coat copper under the Bluetooth-compatible module antenna, or there must be no metal shielding around the antenna
4. The current is too loud
Generally caused by power ground interference, it is recommended that the power amplifier wiring should not be too long, and the Bluetooth-compatible ground and power ground should be separated.
