Overview

There's no AD/DA function on the Raspberry Pi GPIO interface, this may trouble you in the Pi development. However, it won't be a problem anymore. The High-Precision AD/DA Board allows you to add high-precision AD/DA functions to the Raspberry Pi.

Supported Pi

  • Raspberry Pi 1 Model A+
  • Raspberry Pi 1 Model B+
  • Raspberry Pi 2 Model B
  • Raspberry Pi 3 Model B


Features

  • Onboard ADS1256, 8ch 24bit high-precision ADC (4ch differential input), 30ksps sampling rate
  • Onboard DAC8532, 2ch 16bit high-precision DAC
  • Onboard input interface via pinheaders, for connecting analog signal
    • the pinout is compatible with Waveshare sensor interface standard, easy to connect various analog sensor modules
  • Onboard input/output interface via screw terminals, for connecting analog/digital signal
  • Features AD/DA detect circuit, easy for signal demonstration


What's on Board

  1. Raspberry Pi GPIO interface : for connecting with the Pi
  2. AD/DA input/output : screw terminals
  3. AD input : pinheaders, the pinout is compatible with Waveshare sensor interface standard, easy to connect various analog sensor modules
  4. 7.68M crystal
  5. LM285-2.5 : provides reference voltage for the ADC chip
  6. Photo resistor
  7. LED output indicator
  8. 10K potentiometer
  9. DAC8532 : 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
