Raspberry Pi AD/DA Expansion

OVERVIEW

There's no AD/DA function on the Raspberry Pi GPIO interface, it 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

Raspberry Pi 3 Model B+


What's on Board

Raspberry Pi GPIO interface : for connecting with the Pi

AD/DA input/output : screw terminals

AD input : pinheaders, the pinout is compatible with Waveshare sensor interface standard, easy to connect various analog sensor modules

7.68M crystal

LM285-2.5 : provides reference voltage for the ADC chip

Photo resistor

LED output indicator

10K potentiometer

DAC8532 : 16bit high-precision DAC, 2ch

Power indicator

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

ADC testing jumper

DAC testing jumper

Power selection jumper

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


Note : the Raspberry Pi and sensors in the photo are NOT included.
