U41 is the TAS3108 device. U33 is the EEPROM for program and coefficient storage. Digital audio data
(I2S) is input on J12 and output on J22. J11 is used for I2C control, reset signal, and power-supply
voltage. Signals in J11 are duplicated in J21 for further control of a DAC output board or speaker amplifier.
D31, a green LED, indicates that the power-supply voltage is within specifications and that the device is
brought out of reset.
