    Hello everyone,

    I am working on an industrial project that is based on stepper motor system. I have to control 17 stepper motors that means 34 digital outputs (step and direction for every motor). The motors will be driven by their drivers do i need only +5v digital outputs. I need 10 relay outputs, those can also be low voltage dc outputs. I need 17 digital inputs 5v from inductive proximity sensor. 2 points for rs 485 connection to the HMI. 5 analog inputs for potentiometer. I read that controllino mega provides only 61 i/o. But i need more than that. Can someone help me with that? I have seen people connecting two arduinos together but I’m not sure if that would be stable and i even don’t know how to do that with controllino. Any help would be grateful. Sorry for not so good English.

    to increase channel numbers you could add a “I2C” expander.

    There are different types and different numbers of channels. (PCF8574, MCP23017, ecc….)
