excellent
I have purchased several AD cards for raspberry pi over the last year and this is the 1st one where the AD inputs resolution is not compromised with noise. Some of the other boards I have purchased I tossed in the trash after playing with them, they were too noisy to be useful.Note, the 32 bit AD resolution is rarely 32 bits for the chip used on this board. You only get that when sampling at 2.5 sample per second selecting a specific filter. At higher rates the resolution noise increases but matches the chip's documentation. At higher sample rates you can measure voltage to about 1mv accuracy.The demonstration software from waveshare is enough to get you going. It would be much better if they had examples of various modes(especially differential input and pga), removed compiler warnings, and cleaned up their code (it is a mess with necessary functions not defined in header files and redefining symbols declared in /usr/include...) .
