  • There's no Analog-to-Digital/Digital-to-Analog (AD/DA) function on the Raspberry Pi GPIO interface, which can restrict the use of certain components in your project. This High-Precision AD/DA Board allows you to add high-precision AD/DA functions to your Raspberry Pi!

    Note: Sensors pictured but not included!

    Features

    • Standard Raspberry Pi 40-pin GPIO extension header
    • Onboard ADS1256, 8-channel 24-bit high-precision ADC (4ch differential input), 30ksps sampling rate
    • Onboard DAC8552, 2-ch 16-bit high-precision DAC
    • Onboard input interface via pin headers, for connecting analogue signal
    • the pinout is compatible with Waveshare sensor interface standard, easy to connect various analogue sensor modules
    • Onboard input/output interface via screw terminals, for connecting analogue/digital signal
    • Features AD/DA detect circuit, easy for signal demonstration

    What's onboard?

    1. Raspberry Pi GPIO interface: for connecting with the Pi

    2. AD/DA input/output : screw terminals

    3. AD input: pin headers, the pinout is compatible with Waveshare sensor interface standard, easy to connect various analogue sensor modules

    4. 7.68M crystal

    5. LM285-2.5: provides the reference voltage for the ADC chip

    6. Photoresistor

    7. LED output indicator

    8. 10K potentiometer

    9. DAC8552 : 16bit high-precision DAC, 2ch

    10. Power indicator

    11. ADS1256 : 24bit high-precision ADC, 8ch (4ch differential input)

    12. ADC testing jumper

    13. DAC testing jumper

    14. Power selection jumper

    15. ADC reference ground configuration: when AD single inputted, the AINCOM is reference terminal, can be connected to GND or external reference voltage
