  • APPLICABLE: Bluetooth 5.0 power amplifier board with 36x25x10mm / 1.42x0.98x0.39in heatsink, applicable power supply DC12‑24V 5A and above (24V battery pack cannot connected), applicable speakers 20-100W, 4-8 Ω.
  • CAUTIONS: Amplifier board will only have enough output power if the sound input is sufficient and the power supply voltage and current are sufficient. The higher the power supply voltage, the higher the output power, the smaller the speaker impedance, the higher the output power. Please make sure the power of the power supply is greater than the actual power of the amplifier!
