I am using the STC [color = # 444444! Important] microcontroller plus VS1003 do an MP3, but felt more plus an amplifier with a sense, then made a power amplifier with TDA2822.
However, sharing a single-chip power amplifier and the microcontroller and amplifier are not operating. But separate power supply, two can be used.
Is not the power to force? But the power is 5V 1A's. Unreasonable ah.
Ask, which is what causes.
