    Thanks for the image Rob. I'm guessing, but to change to LV we just drop some solder in the hole to bridge it or is this where to attach the 5VDC positive lead?

    You have to "switch" solder bridge to bypass 5V regulator. Remove solder ball from the bridge and add new one on the LV side

    Thanks Rob. It doesn't paint a clear picture on what needs to be done so I'll wait until they arrive and then ask questions from there. Appreciate your time.

    To switch from 12V-24V to 5V:

    1. remove existing solder bridge

    2. all 3 pads should be separate now

    3. solder bridge on the LV side

    BTW, you can use boards with default setting of 12V-24V in 5V environment, but you will not get the full 5V on the data output (it will work, just not as good.)

    Thanks Rob. 100% exactly what I needed to understand what I need to do the switch over. Many thanks.
