Description
- Onboard ADS1256, 8ch 24bit high-precision ADC (4ch differential input), 30ksps sampling rate
- Onboard DAC8552, 2ch 16bit high-precision DAC
- Onboard input/output interface via screw terminals, for connecting analog/digital signal
- Features AD/DA detect circuit, easy for signal demonstration
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 Raspberry Pi High-Precision AD/DA Expansion Board allows you to add high-precision AD/DA functions to the Raspberry Pi.
