The DFRobot Bluetooth board has 5 quality 470uf capacitors that bring you stable output
The board also comes with a heat sink and adopts an excellent power module. The board includes bottom/top protective panels and supports protection mechanisms including overvoltage, under voltage, overheating, short circuit protection, and DC detection. The board will output adequate power only when the audio input and power source voltage/current are sufficient. The higher the power supply voltage, the larger the output power. Besides that, speaker impedance also changes the amplifier board power output.
