#High-Precision AD/DA Board
|
||||
|
||||
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
|
||||
|
||||
- Onboard ADS1256, 8ch 24bit high-precision ADC (4ch differential input), 30ksps sampling rate
|
||||
- Onboard DAC8532, 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
