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.

Features

Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano
Onboard ADS1256, 8ch 24bit high-precision ADC (4ch differential input), 30ksps sampling rate
Onboard DAC8552, 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

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
DAC8552 : 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
