EXPANSION BOARD ADC 24 BIT ADS1256 DAC8532 Raspberry Pi 3B/2B/A+/B+

Product Description

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.
