Allo I2S Isolator v1.2

Galvanic isolator between the minicomputer and the DAC sound card.

Overlay power supply

The isolator requires a 5V main power supply and a clean power supply as an auxiliary. The main power can be supplied in two ways, through the Raspberry or through the built-in USB C connector.

Main power supply

The J26 jumper is used to select the main power source.

  • When this is in place, power is provided via the USB Type C connector. In this configuration, the Raspberry is also powered from the socket mentioned above.
  • Removing the jumper allows the isolator to be powered from within the Raspberry Pi.

Additional (clean) power supply

  • The power is drawn from the DAC cap placed on the galvanic isolator. In order to power the clean side it is necessary to change the jumper on it.
    • Katana DAC: power supply to the galvanic part takes place when the J30 jumper is on.
    • Boss DAC: power supply of the galvanic part is possible when jumper J25 is set.

Built-in PWR LED -by default active when additional power is connected, to disable it remove J29 jumper.

Additional I2C pins - there are additional pins on the board where I2C interface is located, so you can directly connect additional devices like display.
