My favorite combo is to use the Rpi UART with a nano arduino that has 8 ADCs @ 10bit and you can get them for like $5. I like to make the ardiuno dumb with a modbus slave. The combination with the UART/MODBUS is extremely reliable. You can also pump it out to tcp with the mbusd utility.

Some Arduino's give an 8 channel ADC at 10 bits resolution. https://www.arduino.cc/en/Tutorial/Foundations/AnalogInputPins -John Moore On Sun, Oct 25, 2020 at 10:34 AM The MacDougals via TriEmbed <[email protected]> wrote: > I am looking for an 8 channel ADC chip. > 10 bit is sufficient.
