      I may use the 5V for powering miscellaneous things up to 5A. Is this possible? What is the max current I can draw from 5V? For the 12V, it is 2A according to elsewhere in the forum. While we are at it, what is the 3.3V max current draw?

          Yes it's 2A total. Allow 350mA for the Duet WiFi itself, plus the current draw of any PanelDue, Z probe and 3-wire endstop switches etc. that are powered from 5V or 3.3V.
