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.

Hi, there~ as you can see, there is no pin of vref, so the range is 0~3.3V or 0~5V, if you want change the range, you have to make a signal processing circuit, Regards!

Hi,sorry, the voltage range is about 0~5V, and the different range will effect the precision, you can check the datasheet of ads1256, Regards!

Good morning, this product is only the PCB or is the board completely assembled and ready to use with Raspberry ?, it is not understood because the photograph is of the PCB alone. Thanks
