Our expert advises
Bluetooth modules are current and power-sensitive modules, so to avoid problems recommended to take our advice. When building a wireless speaker, or simply a speaker with a Bluetooth module, the most important thing is the power supply. In addition, powering the bluetooth module and amplifier from a single voltage source results in noise. If you have encountered similar problems solder an electrolytic capacitor to the module's power supply - 5V and GND with a capacity of at least 2000uF. Further you can use one of the ways:
- The best option when you want to power the module and amplifier from a single voltage source is to use a Step-Down DC-DC converter, or Step-Up depending on the configuration, and power the module through the converter.
- Voltage separation. We supply the BT module with an independent power source and the amplifier with another one, which gives us a separate ground on the circuits which can reduce interference, but we recommend a less invasive and complicated I solution.

Hello. Everything is clearly described in the product description! Filter the power supply as well as the signal input to the module. It would be best to additionally connect ceramic capacitors of about 100nF to the "L and R" signal inputs and outputs. However, as if even if you stand on your ears and the power supply is noisy, it will still be audible in the speakers.
Hello. If the inverter is regulated then it is best to set 5V or 5.1V evenly larger values may damage the circuit.
