Power to the board is provided through the host Raspberry Pi using the GPIO port. Only one ADC-DAC Pi can be used on a Raspberry Pi but the extended pins on the GPIO connector allow you to stack the ADC-DAC Pi along with other expansion boards.

The A/D and D/A converters communicate with the Raspberry Pi through the SPI interface. 

The ADC-DAC Pi V1.0 is a 2 channel 12 bit analogue to digital converter and 2 channel 12 bit digital to analogue converter designed to work with the Raspberry Pi platform. 

The ADC-DAC Pi is based on the Microchip MCP3202 A/D converter containing 2 analogue inputs with 12 bit resolution with a Microchip MCP4822 dual channel 12-bit DAC with internal voltage reference.

Max ADC Sample Rate: 100 ksamples/sec

Max ADC Sample Rate under Python: 12,000 samples per second.

The ADCDAC Pi is compatible with all Raspberry Pi models.
