For excellent sound quality, the Amplifier Board uses a digital input with high noise immunity and high jitter tolerance. It also provides electromagnetic interference suppression and enables the connection of loudspeakers.

This item uses a high noise immunity digital input with high jitter tolerance

With a filter inductor, the sound is round and clear.

After the power amplifier board is powered, the DC voltage between the two pads of the speaker is 0V, and the DC voltage between the speaker pad and GND is half of the power supply voltage.Hands should not touch the pins of the components on the board, human interference signals interfere with the timing of the digital power amplifier, resulting in damage to the chip. A strong high voltage with static electricity on the human body will break down and damage the chip.

can provide 3W (left channel) +3 W (right channel) output power in the 4 load and 5V power supply conditions
