I posted this in the wrong topic so I've moved it here.
Just got in a 2.4 and a 3.2 Nextion display. I'd seen some comments on the current draw and the possible need for a heat sink on the existing 5V regulator or maybe even a separate supply. So I just measured both on the bench.
Supply voltage was 5.04 VDC.
2.4 display was 125 ma. 3.2 display was 110 ma. Both at full brightness.
These are both above (~25 to 35 or so) what is listed on the manufacturers website.
I did not check with the display in sleep mode.
