      Hi all, I want to connect NPN proximity sensor to Duet3D WiFi 1.03. My sensor is working at 5V. The output line from the sensor in the normal state is 5V, when it is triggered it changes to zero. Can someone tell me what is the maximum voltage on INPUT probe terminal on Duet3D WiFi 1.03?

        3.3V.
        only the 1.04 can handle more.
