One of the modules we want to offer is an analog input module. One problem, there are thousands to ADCs to chose from, ranging from few dollars to $$$ and from 8bit to 24bit!
So what is on your wish list for an analog input module?
Input voltage levels?
Adding A-type sockets for input will increase cost and over complicate things. Is 0.1" header or terminal block okay?
How will you use it? An example application will help very much.
