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.

ΤΟ ΠΑΚΕΤΟ ΠΕΡΙΕΧΕΙ

  1. High-Precision AD/DA Board x1
  2. RPi screws pack (2pcs) x1

ΣΗΜΕΙΩΣΕΙΣ

  • The Raspberry Pi and sensors in the photo are NOT included.

 

  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
