Hi, I sent this message also to your site mail but I think the answer maybe interesting for other readers.
I’d like to use Controllino in a small automation project.
The project foresees many pneumatic valves to be controlled (something around 40) and of course some hardware input devices are required too (buttons, switch, joystick, etc.), or as alternative a small touch (3-4″) industrial screen with spi or i2c interface. A possible idea could be using Nextion display.
We also have the requirement to read a Json settings file from SD card and possibly from the web through wifi.
What type of hardware can you suggest?
And last thing how much is rom/ram capacity for software execution? Same of Arduino?
Final version of the project foresees nr.6 machines using the same hardware.
