We use a flatcable from the Controllino to the screen/SD card. SPI is not really made for over wire transmission and glitches can occur. There is 400V running next to the controllino/screen and even this filtering is not enough. We will move to a shielded cable as well for improved performance. Cable length is about 350mm.
Since the connectors on the Controllino are not pin compatible to Arduino, it would have been good if they were DB25 connectors or something similar. Those are easier and better to connect to and also more robust compared to flatcables. For prototyping, other equipment can be used.
