Description: Raspberry Pi AD/DA ExpansionOverviewThere'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.FeaturesStandard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson NanoOnboard ADS1256, 8ch 24bit high-precision ADC (4ch differential input), 30ksps sampling rateOnboard DAC8552, 2ch 16bit high-precision DACOnboard input interface via pinheaders, for connecting analog signalthe pinout is compatible with Waveshare sensor interface standard, easy to connect various analog sensor modulesOnboard input/output interface via screw terminals, for connecting analog/digital signalFeatures AD/DA detect circuit, easy for signal demonstrationWhat's on BoardRaspberry Pi GPIO interface : for connecting with the PiAD/DA input/output : screw terminalsAD input : pinheaders, the pinout is compatible with Waveshare sensor interface standard, easy to connect various analog sensor modules7.68M crystalLM285-2.5 : provides reference voltage for the ADC chipPhoto resistorLED output indicator10K potentiometerDAC8552 : 16bit high-precision DAC, 2chPower indicatorADS1256 : 24bit high-precision ADC, 8ch (4ch differential input)ADC testing jumperDAC testing jumperPower selection jumperADC reference ground configuration : when AD single inputted, the AINCOM is reference terminal, can be connected to GND or external reference voltageInterface DefinitionPINSYMBOLDESCRIPTION1, 173.3VPower supply (3.3V)2, 45VPower supply (5V)3, 5, 7, 8, 10, 18, 22, 24, 26, 27, 28, 29, 32, 36, 38, 40NCNC6, 9, 14, 20, 25, 30, 34, 39GNDGround11DRDYADS1256 data ready output, low active12RESETADS1256 reset input13PDWNADS1256 sync/power off input, low active15CS0ADS1256 chip select, low active16CS1DAC8552 chip select, low active19DINSPI data input21DOUTSPI data output23SCKSPI clock31, 33, 35, 37GPIOextend to sensor interfacePhotosHigh-Precision AD/DA Board back viewConnecting with RPi A+Connecting with RPi2 BConnecting with sensorsNote : the Raspberry Pi and sensors in the photo are NOT included.DimensionDevelopment ResourcesWiki : https://www.waveshare.com/wiki/High-Precision_AD/DA_BoardPackage containsHigh-Precision AD/DA Board x 1RPi screws pack (2pcs) x 112
