New PT100 Daughter Board

[bazza]

I have just received a version of the PT100 daughter board which now has selection jumpers (good idea). I just want to confirm that for a 2 wire sensor I remove the inner jumpers and connect to the inner two terminals on both sides. I have PT100 on both bed and extruder.

For a 2 wire PT100, use the 2 inner terminals in the block of 4 terminals, and install both jumpers. For a 4-wire PT100, remove the jumpers.

Thanks works O.K

Hi!
Which is better - 3 wires or 4 wires?
3 wires - one wire less. And accuracy?

4 wires is better. The Duet3D daughter board does not support 3-wire connections.
