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

Is this board compatible with Raspberry Pi models and sensor modules?
Yes. The board uses the standard Raspberry Pi 40PIN GPIO extension header and supports Raspberry Pi series boards. The pinout is compatible with the Waveshare sensor interface standard for easy connection to analog sensors.
What are the main AD and DA specifications of the board?
The board includes ADS1256 24bit ADC with 8 channels (4 differential input) and DAC8552 16bit DAC with 2 channels. It supports up to 30 ksps for the ADC and has a 7.68M crystal that provides a reference voltage for the ADC.
How do you connect signals and power to the board?
Analog input interfaces use pinheaders that are compatible with Waveshare sensor interface, and screw terminals are available for analog and digital signals. The 3.3V and 5V power pins and ground pins are exposed on the GPIO header for power and grounding.
Are there indicators and configuration options to know the status and adjust setup?
The board includes a LED power indicator, a photo resistor, and a 10K potentiometer, plus test jumpers for ADC and DAC and a power selection jumper. There is an ADC reference ground configuration option for single input mode.
Where can I find documentation and support for this board?
Documentation and support are available on the Waveshare development resources wiki at www.waveshare.com/wiki/High-Precision_AD/DA_Board.
