      Hi

      I have a CoreS3 which I am trying to get the Env pro sensor working with. The Uiflow 2 example did not work in that it couldn't find the module. I measured the voltage on Port A (red) and it was only 0.5 V. Is it a defective unit?

        Hello @Bipman

        most likely external power is not turned on.

        Try Set external port power to output mode. You'll find that block under System - Power.

        Thanks

          Thanks, I've just tried it and no difference. The code is :-

          I've noticed that the Python code does not change when I add the external port power item in.

          The voltage is still 0.5v though on the port. Am I missing something?

            try adding it after Init built-in hardware at beginning.

            In my case this line was added in the Micropython code:

            Power.setExtOutput(True)
            

            Note: make sure you have set Read mode on the Micropython tab; else blockly changes are not reflected.

            Thanks
