The Bluetooth audio module has a very high power requirement, otherwise it will affect the audio quality. Please ensure that the power supply is added to the LC filter circuit.
Audio Bluetooth is generally not recommended to use a switching power supply.
Third, the module sizePCB size: 22*17*2.4MM (length, width and height)
Pin spacing: 2MMFourth, common problems
1, search for Bluetooth:
Generally caused by power supply interference, the power supply line must be added with LC filter circuit.2: The Bluetooth signal is too weak:
Do not wire or copper under the Bluetooth module antenna, or there should be no metal shielding around the antenna.3: The current sound 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 ground should be separated from the power ground.
