Feature

●Parameter: The operating voltage of the audio amplifier board is DC 5V (does not overpressure, overpressure burns IC), output power is 5W (2Ω 5V)/3W (4Ω 5V)/1.8W (8Ω 5V)
●【Manmade Material】This newly designed power amplifier is made of high capacity filter capacitors for noble black dipped gold circuit boards, speaker capacitors, and channels. In addition, this new amplifier module has been customized with black copper terminal blocks and gold-plated audio input terminal blocks
●【High Performance】Digital amplifier module is more than 90% efficient, less than 10% normal harmonic distortion noise, low static current and noise suppression
●Safety Protection: Reverse power input protection, short circuit, overheating, passing EMI
●【Additional Functions】 You can connect the amplifier type to select different functions (MODE: High power level is Type D, low power level is Type AB. Factory default high power level) External shutdown can be added (SD: chip shuts down at low power level. Factory default high power level)
