Description
Galvanic isolation between minicomputer and DAC sound card in the form of shield for the Raspberry Pi and Sparky, it works with Boss DAC and other converters digital-analog. It works in master and slave mode of I2C, mode can be changed using the switch SW5 located on the board.
The Slave receives signals (I2C, I2S, GPIO) from SBC through a 40-pin connector and isolates the integrated circuits through the digital isolator from Silicon Lab. Then, isolated signals are transmitted to the DAC via 40-pinconnector.
In the Master mode, signals (I2C, I2S and GPIO) from SBC through a 40-pin connector andisolates the integrated circuits through the digital isolator from Silicon Lab.Then, isolated signals are transmitted to the DAC via 40-pin connectorand, at the same time, receives I2S (LRCLK and BCLK) from the DAC via 40-pin connector and isolates through the digital isolator from Silicon Lab. Then, isolated signals are transmitted to the SBC.
The subject of the sale is a shield with a galvanic isolator, minicomputerRaspberry Pican be purchased separately.
The shield with the insulator can be connected to minicomputer Raspberry PiorSparkyusing the GPIO 40-pinconnector, without the need of additional wires. The selection of components and applied circuit was designed to reduce noise and get better sound reproduction.
