Raspberry Pi AD/DA Expansion
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.
Raspberry Pi 1 Model A+
Raspberry Pi 1 Model B+
Raspberry Pi 2 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
LM285-2.5 : provides reference voltage for the ADC chip
LED output indicator
DAC8532 : 16bit high-precision DAC, 2ch
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.
