Overview 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. Supported PiStandard Raspberry Pi 40PIN GPIO extension header, Supports Raspberry Pi A+/B+/2B/3B/3B+/4B and later versions, Jetson Nano Features 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 our 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 Package ContainsHigh-Precision AD/DA Board × 1RPi screws pack (2pcs) × 1
